A hydrolysis constant is an equilibrium constant for a hydrolysis reaction.〔(Definition of hydrolysis_constant - Chemistry Dictionary )〕 For example, if a metal salt such as AlCl3 dissolves in an aqueous solution, the metal cation behaves as a Lewis acid and hydrolyzes the water molecules in the solvent.〔Research and Education Association. ''The best test preparation for the GRE Chemistry test.'', 2000. ISBN 0-87891-600-8. Page 87.〕 :Al3+ + 2H2O → AlOH2+ + H3O+ The hydrolysis constant for this reaction is as shown: :Khydrolysis = () * () / () In a more generalized form, the hydrolysis constant can be described as: :Ka = () * () / () where A− represents any base, and HA represents any acid.〔(Hydrolysis )〕 == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Hydrolysis constant」の詳細全文を読む スポンサード リンク
