Aspirin (acetylsalicylic acid, HC9H2O4) has a value of Ka equal to 3.3x10^-4. What is the pH after 652 mg of aspirin is dissolved in a solution of 237 mL? Set up an ICE table in order to determine the unknown, set up the expression for Ka in order to determine the unknown, and then determine the pH of the solution.
The active ingredient in aspirin is acetylsalicylic acid (HC9H7O4), a monoprotic acid with a Ka of 3.3×10−4 at 25 ∘C . What is the pH of a solution obtained by dissolving two extra-strength aspirin tablets, containing 540 mg of acetylsalicylic acid each, in 360 mL of water? Express your answer to two decimal places.
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
