Calculate [OH⁻], [H⁺], and the pH of 0. 20 M solutions of each of the following amines. a. Triethylamine [(C₂H₅) ₃N, Kb = 4. 0 x 10⁻⁴]
a) [OH⁻] = 5. 0 x 10⁻³ M, [H⁺] = 2. 0 x 10⁻¹¹ M, pH = 10. 70
b) [OH⁻] = 2. 5 x 10⁻⁵ M, [H⁺] = 4. 0 x 10⁻¹⁰ M, pH = 9. 60
c) [OH⁻] = 1. 0 x 10⁻⁴ M, [H⁺] = 4. 0 x 10⁻¹⁰ M, pH = 9. 60
d) [OH⁻] = 1. 0 x 10⁻³ M, [H⁺] = 2. 0 x 10⁻¹¹ M, pH = 10. 30
