The optimum pH of formic acid - formate buffer is 3.75

What is Buffer ?

A substance or a solution which resists any changes in pH, when acid or alkali is added to it.

pH = pKa + log[base] / [acid]

Considering equimolar concentration of acid and base

pH = 3.75 + log(x)/(x)

pH = 3.75 + log (1)

pH = 3.75 + 0

pH = 3.75

Hence,

The optimum pH of formic acid - formate buffer is 3.75
