A graph has to be drawn showing the distribution curve of acetic acid and acetate ion buffer solution. Concept introduction : Buffer solution is defined as a solution that oppose changes in pH while adding little amount of either an acid or a base. In general, addition of acid or base does not affect the pH in buffer solution but if it is more than amount of conjugate base or conjugate acid, then buffer loses its buffering capacity. Buffer solution is a combination of a weak acid and its conjugate base or vice-versa in an aqueous solution. pH is the logarithm of the reciprocal of the concentration of H 3 O + in a solution. pH is used to determine the acidity of an aqueous solution pH = pK a + log [conjugate base] [acid] is Henderson-Hasselbalch equation.

You are studying a clear solution and you added the pH indicator methyl violet. The colour range of the indicator methyl violet in a clear solution when changing from acidic to basic is yellow (pH 0) to blue purple (pH 1) to violet (pH 2). You initial pH of the solution when tested with a pH meter is O.2. You are going to add 250 drops of 0.1 M HCI. Please select the most appropriate answers to the following two questions. What is the initial colour of the solution at pH 0.2? What is the colour of the solution and what will the pH be after the addition of the HCI? Select 2 correct answer(s) The colour of the solution after the addition of HCI will be clear and the pH will be less than 0.2. The colour of the solution after the addition of HCI will be violet and the pH will be higher than 0.2.

Consider the following data on some weak acids and weak bases: name formula HNO₂ 2 4.5 × 10 acetic acid HCH3CO₂ 1.8 × 107 -5 nitrous acid acid solution 0.1 M NH4CI 0.1 M C6H5NH3Br 0.1 M KNO3 0.1 M KNO2 K X 4 pH pla Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. choose one ✓ choose one ✓ choose one ✓ choose one Ś base name formula NH3 aniline C6H5NH₂ 4.3 × 107 10 K₂ ammonia 1.8 × 10 -5 ? 18 Ar

CH3CH2CO2H , Ką = 1.3 x 105 CH3CH2CO2 , Kp = 7.7 x 10-10 F, Kp = 1.4 x 10-11 HF , Ką = 7.2 x 10-4 For the reaction between propanoic acid (CH3CH2CO2H) and a solution containing fluoride ions (F"): (a) The name of the conjugate base produced is (b) The name of the conjugate acid produced is (c) The reaction is favoured (write 'reactant' or 'product'), because the reactants are the (write 'weaker' or 'stronger') set of acid and base.
