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 = 12.2
A. [H+] = 6.31 × 10-13 [OH-] = 1.58 × 10-2 B. [H+] = 1.58 × 10-13 [OH-] = 6.31 × 10-3 C. [H+] = 6.31 × 10-11 [OH-] = 1.58 × 10-3 D. [H+] = 1.58 × 10-2 [OH-] = 6.31 × 10-13
