Buffer Capacity

Buffer Capacity

The effectiveness of a buffer in maintaining pH depends on the relative concentrations of acid and base in the solution
1. A buffer solution with a high concentration of acid and base can neutralise more added base and acid than one with low concentrations
if [weak base] = [weak acid] in a buffer solution, then [H3O+] = Ka and pH = pKa
In any buffer solution, the pH is close to the pKa of the weak acid component when the acid and base have similar concentrations
1. The buffer is effective in the pH range of pKa +/= 1
