Question

Provide the K_a expressions for the ionization of citric acid (H₃C₆H₅O₇).

Accepted Answer

K_a1 = [H₂C₆H₅O₇^–][H₃O⁺]/[H₃C₆H₅O₇]

K_a2 = [HC₆H₅O₇^2–][H₃O⁺]/[H₂C₆H₅O₇^–]

K_a3 = [C₆H₅O₇^3–][H₃O⁺]/[HC₆H₅O₇^2–]

Answer

K_a1 = [H₃O⁺][H₂O]/[H₃C₆H₅O₇][H₂C₆H₅O₇^–]

K_a2 = [H₃O⁺][H₂O]/[H₂C₆H₅O₇^–][HC₆H₅O₇^2–]

K_a3 = [H₃O⁺][H₂O]/[HC₆H₅O₇^2–][C₆H₅O₇^3–]

Answer

K_a1 = [H₃C₆H₅O₇]/[H₂C₆H₅O₇^–][H₃O⁺]

K_a2 = [H₂C₆H₅O₇^–]/[HC₆H₅O₇^2–][H₃O⁺]

K_a3 = [HC₆H₅O₇^2–]/[C₆H₅O₇^3–][H₃O⁺]

Answer

K_a1 = [H₃C₆H₅O₇][H₂C₆H₅O₇^–]/[H₃O⁺][H₂O]

K_a2 = [H₂C₆H₅O₇^–][HC₆H₅O₇^2–]/[H₃O⁺][H₂O]

K_a3 = [HC₆H₅O₇^2–][C₆H₅O₇^3–]/[H₃O⁺][H₂O]
