Hydrolysis

Definition

Hydrolysis is a chemical reaction in which water is used to break down a compound, leading to the formation of new substances. This process plays a vital role in various chemical and biological reactions, particularly those involving ions and coordination complexes, where it can affect stability and reactivity. Additionally, hydrolysis is critical in the context of inorganic polymers, clusters, and the acid-base properties of oxides in aqueous solutions.
