★ FORMULA OF BUFFER INDEX -

$buffer \: index = \frac{no. \: of \: moles \: of \: acid \: or \: base \: added \: in \: 1 \: litre}{change \: in \: ph}$

$\huge\bf\pink{{\mid{\overline{\underline{buffer\: index}}}\mid}}$

A buffer is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases.

▶When an acid or base is added to a buffer system, the effect on pH change can be large or small, depending on both the initial pH and the capacity of the buffer to resist change in pH.

▶The buffer index can be defined as the differential ratio of the increase in the amount of strong acid or strong base added, to pH variation.

Buffer index=no.of moles of acids or bases added in 1 litre/change in pH
