1. Calculate the pH of a 0.405 M aqueous solution of acetylsalicylic acid (aspirin) (HC9H7O4, Ka = 3.0×10-4) and the equilibrium concentrations of the weak acid and its conjugate base. pH = [HC9H7O4 ]equilibrium = M [C9H7O4- ]equilibrium = M 2. Calculate the pH of a 0.0149 M aqueous solution of formic acid (HCOOH, Ka = 1.8×10-4) and the equilibrium concentrations of the weak acid and its conjugate base. pH = [HCOOH]equilibrium = M [HCOO- ]equilibrium = M
