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 CH3CO2–(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 CH3CO2–(aq) and increasing the pH.   3. Some CH3CO2–(aq) will react with H3O+, increasing the concentration of CH3CO2H(aq) and reestablishing the solution equilibrium. a. 1 only b. 2 only c. 3 only d. 1 and 3 e. 1, 2, and 3
