The pH is 1.60.
Explanation:
Hydrochloric acid is a strong acid that completely dissociates in water.
For a 0.025 M HCl solution the concentration of the hydrogen ions,
pH is defined as
Substituting 0.025 into the equation for pH we find that the 0.025 M HCl solution has a pH of -log(0.025) = 1.60.
