Question

Pyrrolidine (C₄H₉N), a common building block used in organic synthesis, has a pK_b of 2.69. For a 0.41 M solution of pyrrolidine, determine the pH and the concentration of all species present (C₄H₉N, C₄H₉NH⁺, H₃O⁺, OH^–).

Accepted Answer

pH = 12.45

[C₄H₉N] = 0.38 M

[C₄H₉N⁺] = [OH^–] = 0.028 M

[H₃O⁺] = 3.6 × 10^–13 M

Answer

pH = 13.59

[C₄H₉N] = 0.11 M

[C₄H₉N⁺] = [OH^–] = 0.29 M

[H₃O⁺] = 3.4 × 10^–14 M

Answer

pH = 12.62

[C₄H₉N] = 0.37 M

[C₄H₉N⁺] = [OH^–] = 0.041 M

[H₃O⁺] = 2.4 × 10^–13 M

Answer

pH = 13.14

[C₄H₉N] = 0.28 M

[C₄H₉N⁺] = [OH^–] = 0.13 M

[H₃O⁺] = 7.9 × 10^–14 M
