A) The pH of a buffer is determined by two factors; 1) The equilibrium constant Ka of the weak acid and 2) the ratio of ...
It explains the pH and buffer capacity of buffered solution.
Maximum buffer capacity: Example problem
The question is attached.
Starting with equation (8.5) show that the maximum buffer capacity occur at pH=pKa.
The units of buffer capacity are mol L^-1. As a consequence of the definitions, buffer capacity is always a positive quantity. For a monoprotic acid the buffer capacity (as a function of pH) is given by: (see attachment).
The buffer capacity depends n both the pH of the buffer and the concentrations of the components of the buffer.View Full Posting Details
