Answer» Correct Answer - C Salts formed by the reactions between acids and bases (in denfinite proporties) undergo dissociation in water. The cation/anions formed on dissociation of salts either exist as hydrated ions in aqueous solutions or interact with water to reform the corresponding acids/bases depending upon the nature of salts. The latter process of interaction between water and cations/anions or both of salts is called hydrolysis. The pH of the solution gets a affected by this interaction. The cations of strong bases such as `Na^(+), K^(+), Ca^(2+)`, and `Ba^(2+)` simply get hydrated but do not hydrolyze. |
