Which of the following is true of the position of the equilibrium established when acetate ions react with hydrogen sulfide as represented below? CH₃COO⁻ + H₂S ⇋ CH₃COOH + HS⁻ A) It lies to the left as the weaker acid and the weaker base are present on the left. B) It lies to the left as the stronger acid and the stronger base are present on the left. C) It lies to the right as the weaker acid and the weaker base are present on the right. D) It lies to the right as the stronger acid and the stronger base are present on the right.

The position of equilibrium will favor the side with the weaker acid and weaker base. In this reaction, the acetate ion is a weaker acid than hydrogen sulfide and the acetate ion is also a weaker base than hydrogen sulfide. Therefore, the equilibrium will lie to the left, favoring the side with the weaker acid (acetate ion) and weaker base (acetate ion).
