Question:

If the pH of a solution is increased from pH 5 to pH 7, it means that the

A) concentration of H+is twice (2X) what it was at pH 5.

B) concentration of H+is half (1/2) what it was at pH 5.

C) concentration of OH-is 100 times greater than what it was at pH 5.

D) concentration of OH-is one-hundredth (0.01X) what it was at pH 5.

E) concentration of H+is 100 times greater and the concentration of OH-is one-hundredth what

they were at pH 5.
