Basic salt formed by the partial neutralization of a strong base by a weak acid is known as a basic salt. They hydrolyse to form a basic solution. It is because when hydrolysis of basic salt takes place, the conjugate base of the weak acid is formed in the solution. pH is less than 7.
Example of basic salt
CH3COONa is a basic salt because it was formed by a strong base (NaOH) and a weak acid (CH3COOH).
- Sodium acetate which is formed in the reaction is basic in nature, so the of this salt is greater than 7.
- Sodium acetate is widely used as a source of carbon for the culturing of many important bacteria.
- This compound is also used as a pickling agent during chrome tanning activities.
