Question

define buffer index​

Answer 1

$\huge\rm{\underline{\red{Answer}}}$

→ 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. The buffer capacity is numerically expressed to be equal with the minimum concentration of strong acid or strong base which causes the variation of buffer's pH with one unit
