Question

Find the pH of 0.0282 M of HClO4

Answer 1

Solution:

HClO₄ is a strong acid in aqueous media therefore it ionizes 100%.

HClO₄ = H⁺ + ClO₄^-

This means that

[H⁺] = [HClO₄] = 0.0282 M.

pH = −log[H⁺].

Therefore,

pH = −log[H⁺] = −log[0.0282] = 1.55

pH = 1.55

Answer: 1.55 is the pH of 0.0282 M of HClO₄.
