For the equilibrium reaction involving acetic acid, which can be described by the reaction below, describe the effect of adding a strong base to the solution, adding more acetic acid to the solution, and adding more water to the solution.

Question

CH3COOH(aq) + H2O(l) ↔ CH3COO-(aq) + H3O+(aq)

Answer 1

Adding a strong base to the solution will shift the equilibrium to the left, decreasing the concentration of CH3COO- and H3O+.

Adding more acetic acid to the solution will shift the equilibrium to the right, increasing the concentration of CH3COO- and H3O+.

Adding more water to the solution will have no effect on the equilibrium since water is a product of the reaction.
