Question

Define the term Buffer index.

Answer 1

Buffer index : Buffer index ‘β’ is defined as the number of gram equivalents of acid or base added to one litre of the buffer solution to change its pH by unity.

β=dB/d(pH)

Here,

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.
