Answer:

pH = 4.6

Explanation:

As hydrochloric acid (HCl) is a strong acid, the molar concentration of H⁺ species is the same as the molar concentration of the HCl solution. In other words:

[H⁺] = 2.51x10⁻⁵ M

With the information above in mind we can calculate the pH:

pH = -log[H⁺]

pH = -log(2.51x10⁻⁵ M)

pH = 4.6
