WebBuffer Solutions - Professor Rob Beynon 2004-03-01 An indispensable guide to buffers and to understanding the principles behind their use. Helps the user to avoid common errors in preparing buffers and their solutions. A must for researchers in the biological sciences, this valuable book takes the time to explain something often taken for granted - WebSolution: 1) This is a buffer solution, with a weak base (the ammonia) and the salt of the weak base (the ammonium chloride) in solution at the same time. We will use the Henderson-Hasselbalch Equation to solve this problem. pH = pK a + log [base / acid] 2) We know the two concentrations: pH = pK a + log [0.25 / 0.35]

WebProblem : Explain why the p Ka of a buffer should be as close as possible to the desired pH. The p Ka should be quite close to the desired pH so that the ratio of base to acid in the Henderson-Hasselbalch equation will be close to 1. As the ratio of base to acid deviates from 1, the addition of acids and bases to the buffer will have a more ...
