Concept of hydrolysis

When a salt is dissociated in water, it dissociates completely into its constituent ions. The solvent water dissociates slightly as,

Pure water is neutral and $[\mathrm{H_3O^{+}}] = [\mathrm{OH^{-}}]$. If the ions of the salt do not interact with water, the hydronium and hydroxyl ion concentrations remain equal and the solution is neutral. When one or more of the salt ions react with water, the equality of concentrations of $\mathrm{H_3O^{+}}$ and $\mathrm{OH^{-}}$ ions is disturbed. The solution does not remain neutral and becomes acidic or basic depending on the type of the salt. Such a reaction between the ions of salt and the ions of water is called hydrolysis of salt. **Hydrolysis of salt is defined as the rea …
