0.250 moles of a weak acid, HA, is dissolved in pure water to make up 500 ml of a solution. As the HA dissolves, the following equilibrium is established: HA(aq) + H2O (l) = H3O+(aq) + A- (aq) K=3.5 * 10-5 (25 C) A). Calculate the concentrations of HA, H3O+, and A- present at equilibrium B). Calculate the pH of the solution at equilibrium.

± Determining the pH of a Weak Base and the Percent Ionization of a Weak Acid Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency of a weak acid or base to ionize can be quantified in several ways including Ka or Kb, pKa or pKb, and percent ionization*. *This assumes that species of equal concentrations are being compared as percent ionization is affected by concentration. Part A Pyridine is a...
