What is the pH of a 2.0 M solution of HNO3?

1 answer

The pH of a solution can be calculated using the formula

pH = -log[H+]

HNO3 is a strong acid and completely ionizes in water to release H+ ions. Therefore, the concentration of H+ ions in a 2.0 M solution of HNO3 is 2.0 M.

pH = -log(2.0) = -0.3010

Thus, the pH of a 2.0 M solution of HNO3 is approximately 0.301.
