R3.1 (AHL) Buffer solutions
This section covers the chemistry of buffer solutions. It describes how they can resist a change in pH when small amounts of an acid or alkali are added to the solution or when the solution is diluted. It explains how their pH depends upon the pKa or pKb of the weak acid or base and the ratio of the concentration of acid or base to the concentration of the conjugate base or acid. What happens when protons are...
