H2o ka value

The equilibrium constant Kb for a base is usually defined as the association constant for protonation of the base, B, to form the conjugate acid, HB . Using similar reasoning to that used before Kb is related to Ka for the conjugate acid. In water, the concentration of the hydroxide ion, [OH ], is related to the concentration of the hydrogen ion by Kw = [H ][OH ], therefore WebJan 30, 2024 · Howto: Solving for Ka.
