Multiple Choice

Consider the ionization of acetic acid as follows:CH ₃COOH + H₂ O H₃O + + CH₃COO 1 - What is the effect of adding the common ion, acetate, CH₃COO - (source:
CH₃COONa) , to this equilibrium system?

A) The equilibrium shifts to the left and the pH rises.
B) The equilibrium shifts to the right and the pH rises.
C) The equilibrium shifts to the left and the pH lowers.
D) The equilibrium shifts to the right and the pH lowers.
E) Nothing happens. The pH remains constant and the equilibrium does not shift in either direction.
