Question

What is the pH of 0.001 M HNO3 solution ? Please give explanation.​

Answer 1

Given:

0.001M of nitric acid.

To find:

We have to the pH.

Solution:

To determine the pH of the nitric acid solution we have to follow the below steps as follows-

Nitric acid dissociates as-

$HNO_3\rightarrow H^++NO_3^-$.

Thus the concentration of hydrogen ions is also 0.001M.

The pH of the nitric acid solution is given as-

$pH=-log [H^+]$.

$[H^+]=0.001$

$pH=-log(0.001)\\pH=3$

The pH of the nitric acid solution is 3.
