Question

The pH equation is pH = -log [H+] It is a log base 10 equation. How does the concentration of a pH 5 solution compare to a pH 6 solution?

Answer 1

Because it is log base 10, the concentration of a solution with pH 5 will be 10 x greater than that with a pH of 6

pH 5 has [H⁺] = 1x10^-5 M

pH 6 has [H⁺] = 1x10^-6 M

Answer 2

The concentration of H⁺ for a pH of 5 is 1*10^-5 M, which is greater than the concentration of H⁺ for a pH of 6, which is 1*10^-6 M.
