Define buffer capacity and buffer index |
|
Answer» 1. The buffering ability of a solution can be measured in terms of buffer capacity. 2. Buffer index, as a quantitative measure of the buffer capacity. 3. It is defined as the number of gram equivalents of acid or base added to 1 litre of the buffer solution to change its pH by unity. 4. β = \(\frac{dB}{d(pH)}\) .dB = number of gram equivalents of acid / base added to one litre of buffer solution. d(pH) = The change in the pH after the addition of acid / base. |
