Question

Calculate the $p H$ of the solution to the nearest integer.

Open in App

Solution

Given, a buffer solution was prepared by dissolving $0.05$ mol formic acid and $0.06$ mol sodium formate in enough water to make $1 L$ as solution.
$p H = p K_{a} + l o g \frac{[s a l t]}{[a c i d]} = p K_{a} + log \frac{0.06}{0.05}$
$p H = 3.744 + log 1.2 = 3.823$
Hence, the answer to the nearest integer is $4$ ,
