Use the pH scale to solve the problem. Negative ions, designated by the notation [OH-] are always present in any acid or base. The concentration, [OH-], of these ions is related to [H+] by the equation [OH-] ? [H+] = 10-14 moles per liter. Find the concentrations of [OH-] and [H+] in moles per liter for the substance with the following pH value. Round to two decimal places. pH = 12.3
A. [H+] = 2.00 × 10-13
[OH-] = 5.01 × 10-3
B. [H+] = 5.01 × 10-11
[OH-] = 2.00 × 10-3
C. [H+] = 5.01 × 10-13
[OH-] = 2.00 × 10-2
D. [H+] = 2.00 × 10-2
[OH-] = 5.01 × 10-13
