Question

Provide the K_{a} expressions for the ionization of citric acid ($$H_{3}C$$_{6}$$H_{5}O$$_{7}).

Accepted Answer

K_{a1} = [$$H_{2}C$$_{6}$$H_{5}O$$_{7}^{–}][$$H_{3}O$$^{+}$$]/[H$$_{3}$$C_{6}H$$_{5}$$O_{7}]K_{a2} = [HC$$_{6}$$H_{5}O$$_{7}^{2–}][$$H_{3}O$$^{+}$$]/[H$$_{2}$$C_{6}H$$_{5}$$O_{7}^{–}]K_{a3} = [C$$_{6}$$H_{5}O$$_{7}^{3–}][$$H_{3}O$$^{+}$$]/[HC$$_{6}$$H_{5}O$$_{7}^{2–}]

Answer

K_{a1} = [$$H_{3}O$$^{+}$$][H$$_{2}$$O]/[H$$_{3}$$C_{6}H$$_{5}$$O_{7}][H$$_{2}$$C_{6}H$$_{5}$$O_{7}^{–}]K_{a2} = [H$$_{3}$$O^{+}$$][$$H_{2}O$$]/[$$H_{2}C$$_{6}$$H_{5}O$$_{7}^{–}][$$HC_{6}H$$_{5}$$O_{7}^{2–}]K_{a3} =  [H$$_{3}$$O^{+}$$][$$H_{2}O$$]/[$$HC_{6}H$$_{5}$$O_{7}^{2–}][C$$_{6}$$H_{5}O$$_{7}^{3–}]

Answer

K_{a1} = [$$H_{3}C$$_{6}$$H_{5}O$$_{7}]/[$$H_{2}C$$_{6}$$H_{5}O$$_{7}^{–}][$$H_{3}O$$^{+}$$]K_{a2} = [H$$_{2}$$C_{6}H$$_{5}$$O_{7}^{–}]/[HC$$_{6}$$H_{5}O$$_{7}^{2–}][$$H_{3}O$$^{+}$$]K_{a3} = [HC$$_{6}$$H_{5}O$$_{7}^{2–}]/[$$C_{6}H$$_{5}$$O_{7}^{3–}][H$$_{3}$$O^{+}$$]

Answer

K_{a1} = [$$H_{3}C$$_{6}$$H_{5}O$$_{7}][$$H_{2}C$$_{6}$$H_{5}O$$_{7}^{–}]/[$$H_{3}O$$^{+}$$][H$$_{2}$$O]K_{a2} = [H$$_{2}$$C_{6}H$$_{5}$$O_{7}^{–}][HC$$_{6}$$H_{5}O$$_{7}^{2–}]/[$$H_{3}O$$^{+}$$][H$$_{2}$$O]K_{a3} =  [HC$$_{6}$$H_{5}O$$_{7}^{2–}][$$C_{6}H$$_{5}$$O_{7}^{3–}]/[H$$_{3}$$O^{+}$$][$$H_{2}O$$]
