What is difference between a pH of 8 and a pH of 12 in terms of H+ concentration?
Katena32 [7]

Answer:

At a greater value of pH, [H⁺] is really low.

Solution with pH = 8 has more [H⁺] than solution at pH =12.

Explanation:

pH = - log [H⁺]

10^-pH = [H⁺]

At pH = 8, [H⁺] = 10⁻⁸  → 1×10⁻⁸ M

At pH = 12, [H⁺] = 10⁻¹²  → 1×10⁻¹² M

In conclussion, at a greater value of pH, [H⁺] will be really low.

Solution with pH = 8 has more [H⁺] than solution at pH =12.
