87. explain what hydrolysis is.

Brief Explanations:

Hydrolysis is a chemical reaction where a compound reacts with water. It often involves the breaking of a chemical bond in the compound by the addition of the components of water ($H^+$ and $OH^-$). In organic chemistry, it can break down esters, amides etc. In inorganic chemistry, metal - salt hydrolysis can affect solution pH.

Answer:

Hydrolysis is a chemical reaction between a compound and water, often involving bond - breaking and addition of water components.
