Lecture 21 – Cations, Anions and Hydrolysis in
... Hydrolysis involves further chemical reaction of hydrated ions with the solvent (water). Metal ions in aqueous solution behave as Lewis acids. The positive charge on the metal ion draws electron density from the O-H bond in the water. This increases the bond's polarity making it easier to break. Whe ...
