What is pH of 0.03 M hydrochloric acid (HCl) solution.

Hydrochloric acid is a strong acid that dissociates in water to produce chloride and hydronium (H₃O⁺) ions. The pH of a strong acid solution can be calculated using the following equations:

pH = - log [H₃O⁺]

[H₃O⁺] = [strong acid] = 0.03

pH = - log 0.03 =1.52
