System is at equilibrium.
Acid increases hydronium ion concentration. Equilibrium shifts to the left to offset the increase. The propionic acid conc increases, while propionate decreases. Assume no volume change with the addition of sodium acetate. The more polar is the OH bond, the stronger the acid in water.
