a) What is the pH of an aqueous solution with a hydrogen ion concentration of [H ] = 1.6 × 10-9 M?

b) What is the hydroxide ion concentration, [OH-], in an aqueous solution with a hydrogen ion concentration of [H ] = 1.6 × 10-9 M?

c) A monoprotic acid, HA, dissociates: HA<-->H^+ + A^- The equilibrium concentrations of the reactants and products are [HA] = 0.120 M [H ] = 2.00 × 10-4 M [A-] = 2.00 × 10-4 M Calculate the Ka value for the acid HA.
