. How does the hydronium ion concentration in a solution with a pH of 2 compare to that with a pH of 5?

-The solution with a pH of 2 has 3 times more hydronium
-The solution with a pH of 2 has 1000 times more hydronium
-The solution with a pH of 5 has 3 times more hydronium
-The solution with a pH of 5 has 1000 times more hydronium

The higher the hydronium ion concentration of a solution, the lower its pH.

Explanation:

Consider a high hydronium concentration, 1 mol·L⁻¹.

pH = -log[H₃O⁺] = -log1 = 0

Now consider a low hydronium ion concentration, 10⁻¹⁴ mol·L⁻¹.

pH = -log(10⁻¹⁴) = 14

Thus, a high hydronium ion concentration means a low pH.
