Question

An acid-base equilibrium system is created by dissolving 0.50 mol CH₃CO₂H in water to a volume of 1.0 L. What is the effect of adding 0.50 mol CH3CO^2–(aq) to this solution?

1.The pH of the solution will equal 7.00 because equal concentrations of a weak acid and its conjugate base are present.

2.Some CH₃CO₂H(aq) will ionize, increasing the concentration of CH₃CO^2–(aq) and increasing the pH.
3.Some CH₃CO^2–(aq) will react with H₃O⁺, increasing the concentration of CH₃CO₂H(aq) and reestablishing the solution equilibrium.

b. 2 only c. 3 only d. 1 and 3 e. 1, 2, and 3
