Question

Calculate the OH− concentration in each of the following solutions in which the H+ concentrations are

Answer 1

Answer:

see explanations

Explanation:

Use Kw = [H⁺][OH⁻] => [OH⁻] = Kw/[H⁺]; Kw = 1.0 x 10⁻¹⁴

a. [OH⁻] = (1.0 x 10⁻¹⁴/3.5 x 10⁻⁸)M = 2.86 x 10⁻⁷M

b. [OH⁻] = (1.0 x 10⁻¹⁴/0.0065)M = 1.54 x 10⁻¹²M
