If the PH of a Solution Is Increased from PH

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

A) concentration of H⁺ is twice (2×) what it was at pH 5.
B) concentration of H⁺ is one-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 (0.01×) what it was at pH 5.
E) concentration of H⁺ is 100 times greater than what it was at pH 5.
