List of Electrolytes

List of Electrolytes List of Electrolytes Definition of an Electrolytes: An electrolyte is a substance that ionizes into positive and negative ions when dissolved in an aqueous solution. These free ions in a solution consists of the property of conducting electricity in the aqueous state. The strength of the electrolyte depends on its ability to disassociate and conduct electricity. There are basically three types of electrolytes: Strong Electrolyte: A strong electrolyte when dissolved in water forms a solution that is a very good conductor of electricity. This implies that a strong electrolyte is a solute that completely or near to complete dissociates into all its ions in the solution. At the same temperature a solution of strong electrolytes has greater vapor pressure than pure water. Strong electrolytes include strong acids, strong bases and ionic salts. Mentioned below in the table are few examples for strong electrolytes: Strong Electrolyte Name List of Acids HCl Hydrochloric acid HBr Hydro-bromic acid HI Hydro Iodic acid HIO4 Per Iodic Acid H2SO3 Sulphurous acid H2SO4 Sulphuric acid HNO3 Nitric acid HBrO3 Bromic Acid HBrO4 Perbromic Acid HClO3 Chloric acid HClO4 Per-chloric acid List of Bases LiOH Lithium Hydroxide NaOH Sodium Hydroxide KOH Potassium Hydroxide Ba(OH)2 Barium Hydroxide Ca(OH)2 Calcium Hydroxide Sr(OH)2 Strontium Hydroxide RbOH Rubidium Hydroxide CsOH Caesium Hydroxide Mg(OH)2 Magnesium Hydroxide NaH2 Sodium Amide NaH Sodium Hydride List of salts NaNO3 Sodium Nitrate NaCl Sodium Chloride LiCl Lithium Chloride KCl Potassium Chloride CuSO4 Copper Sulfate KNO3 Potassium Nitrate CaCl2 Calcium Chloride CH3COONa Sodium Acetate NaHCO3 Sodium Bi-carbonate AgNO3 Silver Nitrate The dissociation of the strong electrolyte occurs in one direction, which implies it is not reversible. The below equation is mentioned in an aqueous state because a strong electrolyte conducts electricity only in an aqueous state. Cations and Anions: The ions can be classified into two types the cations and the anions. The cations are positive changed ions which are formed by the loss of electrons. The anions are negatively changed ions which are formed by gain of electrons. Here is an example showing the disassociation of NaCl in water. This gives rise to two ions the sodium cation and the chloride anion in an aqueous solution. The disassociation is not reversible as NaCl is a strong electrolyte. Weak Electrolyte: The electrolytes in which the solute does not completely dissociate in the solution is called a weak electrolyte. This implies in such solutions there are disassociated ions as well as molecules of the electrolytes. Therefore the weak electrolytes ionize less in aqueous solutions and conduct very less amount of electricity. Mentioned below in the table is a list of few weak electrolytes: Weak electrolytes Name Acids CH3COOH Acetic Acid H2CO3 Carbonic Acid H2CrO4 Chromic Acid HF Hydrofluoric Acid C6H5COOH Benzoic Acid HNO2 Nitrous Acid H3PO4 Phosphoric acid H(C3H5O3) Lactic Acid (COOH)2 Oxalic Acid Bases NH3 Ammonia NH4OH Ammonium Hydroxide HCN Hydrogen Cyanide C5H5N Pyridine (CH3)2NH Dimethylamine (CH3)3N Trimethylamine C2H5NH2 Ethylamine C2H3N2 Glycine The disassociation of a weak electrolyte is usually an equilibrium equation. This is because the weak electrolytes partially disassociate into positive and negative ions. Mentioned below are two examples for the disassociation of a weak electrolyte: The Hydrogen cyanide when dissolved in an aqueous solution disassociates partially being a weak electrolyte. The HCN disassociates into a hydrogen cation and a cyanide anion in an aqueous state. The Ammonium hydroxide disassociates into an ammonium cation and a hydroxide anion in an aqueous state. Non-Electrolyte: A substance which when dissolved in water lacks ions due to which there is no disassociation is called Non-electrolyte. A non-electrolyte has no ionization therefore it cannot conduct electricity. Most non-electrolytes are polar or non-polar molecules as they dissolve in water as molecules but do not dissociate as ions. Non Electrolyte Name O2 Oxygen SO2 Sulphur dioxide CO2 Carbon dioxide CS2 Carbon disulphide CCl4 Carbon tetrachloride H2O Water CH3OH Methanol C2H5OH Ethanol C12H22O11 Sucrose C6H12O6 Glucose NH2CONH2 Urea CH2Cl2 Dichloromethane CH3H8O3 Glycerol Electrolysis: Electrolysis is the process of passing current through a solution of an electrolyte. In this process of electrolysis the negative and positive ions move towards their respective electrodes. The electrode attracts the ions of the opposite charge towards itself. Electrolytic cell: The Electrolytic cell, is where the process of electrolysis is conducted. The electrolytic cell consists of a beaker which is filled with the electrolytic solution. This cell is then connected to two conducting plates called the anode and the cathode. The anode is a positive electrode that extracts electrons from the negatively charged ions which are the anions. The cathode is a negative electrode that provide electrons to a positively charged ions called the cations. These two electrodes are connected to the D.C power supply terminals. The electric current enters through the positive electrode which is the anode passes through the electrolytic solution and leaves through the cathode. The process of oxidation which is the loss of electrons takes place at the anode. The process of reduction which is the gain of electrons takes place at the cathode. What exactly do the electrolytes do? A body cannot function without the electrolytes due to the important role they play in the cells. They regulate the nerve and the muscle function in the body. They help in maintaining stability in the cells and generate energy when required. They control the body hydration, the pH levels in the blood and the blood pressure. They responsible for rebuilding the damages tissues. The electric tissues in the body are muscles and neurons. Electrolytes activate these electric tissues by: o Extracellular fluid (The fluid outside the cells.) o Interstitial fluid (The fluid inside the cells.) o Intra cellular fluid. (The fluid between the cells.) The calcium (ca2+), Sodium (Na+) and potassium (K+) are required for muscle contractions. The kidneys and other hormones present in the body ensure the electrolyte levels are balanced in the body. Exercise helps in losing the ions such as sodium and potassium and retain the balance. Eating a balance food especially the fresh fruits and vegetables regains the lost sodium and potassium levels in the body.

A Test Prep Timeline for AP Exams

A Test Prep Timeline for AP Exams In 2014, the College Board Advanced Placement exams will take place during the first two weeks of May. It is a wise idea to determine your test date well ahead of time so you can begin preparing. However, as the majority of students enroll in an AP class prior to an AP exam, you may have begun your review in September. As the actual test date approaches, you will need to extend your preparations far beyond your required coursework if you hope to earn a high score. Here are some great tips for AP exam prep. Week One Ideally, your preparation for your AP test should begin one and a half months before the actual exam. For the first week of preparation, focus on gathering together all of your notes and relevant materials. Organize these materials in a way that makes them easy to study. For example, for a history test, sequence your notes from the earliest historical date to the most modern. For biology, consider ordering them from molecules and cells, to organ systems, to organisms, to ecosystems. Use this first week of preparation as your preparing to prepare week. Purchase any review books you may need, fill in any information you may have omitted, and ensure your notes are highlighted and organized. Week Two Your second week of preparation should establish what you do and do not know. Complete a diagnostic AP exam. As you progress through the exam, make note of any question that touches on an unfamiliar topic or to which you do not know the answer. Look at your final score, but rather than paying attention to the fact that you earned a 3 or a 4, determine which questions you answered incorrectly, which you made note of during the exam, and which you understood. Compile a list of your trouble topics and then flag their corresponding areas in your notes. Create a list of the areas in which you are most comfortable, and flag those as well. Deciding upon what you must study intricately and what you must only lightly review will save you time in later weeks. Weeks Three and Four In your third and fourth weeks of preparation, re-examine your notes and study materials, paying particular attention to the problem areas you previously flagged. At the conclusion of each topic, answer several AP exam practice problems to acclimate to viewing the material in a test format. Review any areas that are still difficult with a study group, teacher, or tutor. You should also begin learning how to respond to open-ended questions during weeks three and four. Locate essay or open-ended problems pertinent to the topics you have studied. After attempting the questions, grade them according to the AP rubric. Did you draw from the sources in your U.S. History Document-Based Question? Did you write the correct equations and additional information for your Calculus AB question before you solved the problem? This period of preparation should be your most intense. Here are 4 myths about AP exam prepthat you should be aware of. Weeks Five and Six In the fifth week of your review, sit for a complete AP exam, again flagging any challenging problems. Observe where you must still study. Note, too, where you have improved. Use the sixth week of preparation to solidify any lingering concerns. Answer questions about these topics, and tackle one last set of open-ended prompts before the test. Avoid a cram session the night before the exam, and arrive rested. Six weeks of hard work after a yearlong class prepared you well to succeed on this test.

English Comparatives and Superlatives with Football (Pele vs Maradona)

English Comparatives and Superlatives with Football (Pele vs Maradona) Well, as many of you know we are from the United States but live in Argentina. Of course in the United States football isnt such an important sport and for Argentina it is probably more important than anything else in life, seriously, more important than your wife, than food, than politics, than your job. So today we are learning about comparatives and superlatives in football. Argentina just beat the world cup winner Spain yesterday in a match.ComparativesWe use comparatives to compare two people or things.Short Adjectives-we add er to the end of the adjective: fatter, skinnier, older, younger, smarter, prettier, nicer, etc. (notice the spelling change for words that end in y. Change the y to ier. For example pretty changes to prettier.   Also notice if it is a short word that has a vowel followed by a consonant we double the consonant. For example Fat changes to Fatter.Long Adjectives-we add more before the adjective: more intelligent, more beautiful, more generous, more productive , etc.There are three irregular adjectives: Good, Bad, and Far they change to better, worse, and farther or further.In A Question: Who is better at football Diego Maradona or Pele?Using irregular Adjectives:I think Maradona was a better player, because I live in Argentina.Using regular short Adjectives:I think Maradona is faster than Pele but I think Pele is a more intelligent player.Using regular long Adjectives:Maradona is more controversial than Pele.Superlatives:We use superlatives to compare three or more things 3+.Short Adjectives-we add est to the end of the adjective: fattest, skinniest, oldest, youngest, smartest, prettiest, nicest, etc. (notice the spelling change for words that end in y. Change the y to iest. For example pretty changes to prettiest.   Also notice if it is a short word that has a vowel followed by a consonant we double the consonant.

Important Factors in An Exam Prep Program

Important Factors in An Exam Prep Program Applying to college is exciting and nerve-racking for teens. All of the hard work of high school becomes incredibly important as teens bring it all togetherthe transcript, grade point average, letters of recommendation and moreand assemble their applications. College entrance exam scores are a significant factor in admission too. Make sure your teen prepares effectively for the SAT or ACT with an exam prep program. What should you look for when selecting one? Here are six musts: Customized for each student Studying for the SAT or ACT is made easier when teens know their individual strengths and weaknesses and can focus their study plan. Parents should make sure that their teens receive a diagnostic evaluation at the start of any exam prep program. That assessment of subject-matter knowledge and skills will serve as the baseline for the study program. Structured and scheduled The most effective exam prep program will be scheduled based on teens precise needs in each exam subject and overall score goals (which might be driven by their college of choice). Certain subjects might need more attention than others, and thus, more time and focus. Highly knowledgeable teachers Studying for the SAT and/or ACT is different than studying for a regular test. Its best to work with tutors who are trained in college entrance exam prep. Teens will learn the best working with tutors who know the exams well and understand both the unique structure of each exam and the best strategies for exam preparation and success. A focus on test-taking strategies for each exam The SAT and ACT are similar in what they cover, but there are many distinctions teens need to understand in order to adjust their approach to each exam. For example, students cannot use a calculator on the SAT math test. And in the reading test, students get 22.5 more seconds per question on the SAT than on the ACT. Bottom line: knowing such differences (and how to approach different parts of the exams) is critical. Test practice The best test prep programs incorporate full-length, timed, practice exams. These help teens get comfortable pacing themselves on different question types and allow them to get a feel for the actual exam setting. Prep materials for outside practice Lets face it: to boost their SAT/ACT scores, teens need to put in the work outside of the hours theyre with their exam prep tutor. Additional resources and materials help teens practice questions and focus on areas/subjects on their own time. Not all SAT and ACT prep programs are created equal. If you decide your teen needs individualized help, make sure you invest in a proven test prep program that has helped many high school students perform their best. Huntingtons SAT and ACT preparatory programs are individualized for each students needs and focused on guiding students toward achieving success.
