If solution A has a pH that is four pH units greater than that of solution B, the H₃O⁺ concentration in solution B is 10⁴ times greater than that of solution A.

The pH of a solution is given by:

$pH = -log([H_{3}O^{+}])$

Solution A has a pH that is four pH units greater than that of solution B, so:

$pH_{A} = pH_{B} + 4$

$pH_{B} = pH_{A} - 4$

The H₃O⁺ concentration of solution B is related to that of solution A as follows:

$[H_{3}O^{+}]_{B} = 10^{-pH_{B}}$

$[H_{3}O^{+}]_{B} = 10^{-(pH_{A} - 4)}$

$[H_{3}O^{+}]_{B} = 10^{-(-log[H_{3}O^{+}]_{A} - 4)}$

$[H_{3}O^{+}]_{B} = 10^{(log[H_{3}O^{+}]_{A} + 4)}$

$[H_{3}O^{+}]_{B} = 10^{4}[H_{3}O^{+}]_{A}$

Therefore, the H₃O⁺ concentration in solution B is 10⁴ times greater than that of solution A.

10⁴

Explanation:

There is usually a 10-time fold change in H₃O+ ions from one pH level to the other. The lower the pH level the higher the H₃O+ ions. Therefore for solution A that has a pH that is four pH units greater than that of solution B, then solution B will have;

10⁴ more H₃O+ ions than solution A
