Hydrolysis Reaction

                    Hydrolysis is a chemical reaction that involves a salt reacting with water to produce hydrogen ions and hydroxide ions. It is a type of decomposition reaction one reactant is water. Hydrolysis means " water separation ".
Example:

CH₃COOH    +   H₂O   →   H₃O⁺   +   CH₃COO^-

NH₃   +   H₂O     →    NH₄⁺   +    OH^-

H₂SO₄   +   H₂O    →   H₃O⁺   +   HSO4^-

HCN   +   H₂O   →   H₃O⁺   +   CN^-
