Answer:

A. 2.5 × 10⁻⁴ mol·L⁻¹

Explanation:

pH = -log[H₃O⁺]

[tex][\text{H}_{3}\text{O}^{+}] = 10^{- \text{pH}} \text{ mol/L}[/tex]

pH = 3.60

[tex][\text{H}_{3}\text{O}^{+}] =10^{-3.60}\text{ mol/L}[/tex]

[tex][\text{H}_{3}\text{O}^{+}] = 2.5 \times 10^{-4}\text{ mol/L}[/tex]

The hydronium concentration of a solution with a pH of 3.60 is [tex]2.5 \times 10^-^4 M[/tex]. The correct option is A.

What is pH?

PH is a scale for the measurement of the acidic and basic solutions. The pH of less than 7 are acids and more than 7 are bases.

[tex]\rm pH = -log[H_3O^+]\\\\H_3O^+ = 10^-^p^H\; mol/l[/tex]

pH = 3.60

[tex]\rm H_3O^+ = 10^-^3^.^6^0\\\\H_3O^+ = 2.5 \times 10^-^4 M[/tex]

Thus, the correct option is A.
