E)5 × M

Quizplus · Accepted Answer

The pH of a solution is defined as the negative logarithm of the hydrogen ion concentration, so:

pH = -log[H+]

Rearranging this equation gives:

[H+] = 10^-pH

Substituting pH = 8.7 gives:

[H+] = 10^-8.7 = 2 × 10^-9 M

Therefore, the [H+] of the solution with pH = 8.7 is 2 × 10^-9 M.
