Question

Pyrrolidine ($$C_{4}H$$_{9}$$N), a common building block used in organic synthesis, has a pK_{b} of 2.69. For a 0.41 M solution of pyrrolidine, determine the pH and the concentration of all species present (C$$_{4}$$H_{9}N$$, $$C_{4}H$$_{9}$$NH^{+}$$, $$H_{3}$O^{+}$$, $$OH^{–}).$$

Accepted Answer

pH = 12.45[$$C_{4}H$$_{9}$$N] = 0.38 M[C$$_{4}$$H_{9}N$$^{+}$$] = [OH$$^{–}$$] = 0.028 M[H$$_{3}$$O^{+}$$] = 3.6 × $$10^{–13} M$$

Answer

pH = 13.59[$$C_{4}H$$_{9}$$N] = 0.11 M[C$$_{4}$$H_{9}N$$^{+}$$] = [OH$$^{–}$$] = 0.29 M[H$$_{3}$$O^{+}$$] = 3.4 × $$10^{–14} M$$

Answer

pH = 12.62[$$C_{4}H$$_{9}$$N] = 0.37 M[C$$_{4}$$H_{9}N$$^{+}$$] = [OH$$^{–}$$] = 0.041 M[H$$_{3}$$O^{+}$$] = 2.4 × $$10^{–13} M$$

Answer

pH = 13.14[$$C_{4}H$$_{9}$$N] = 0.28 M[C$$_{4}$$H_{9}N$$^{+}$$] = [OH$$^{–}$$] = 0.13 M[H$$_{3}$$O^{+}$$] = 7.9 × $$10^{–14} M$$

Pyrrolidine (C4H9N), a common building block used in organic synthesis, has a pKb 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–).

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^–).
