acid-dissociation equilibrium constant‚ Ka. Generic Equation: HA(aq) + H20(l) ↔ H3O+(aq) + A-(aq) Therefore‚ Ka = [H3O+][A-]/HA When a strong acid dissolved in water‚ the acids reacts extensively with water to form H3O+ and A- ions. The product of the concentrations for both these ions is larger than the concentration of HA molecules‚ therefore Ka for a strong acid is greater than 1. Example: The Ka of Hydrochloric acid is 1x10^6 HCL + H2O ↔ H3O+ + Cl- … Ka can be used to distinguish between strong
