Give an example of a basic salt.

CH₃COONa is a basic salt because it was formed by a strong base (NaOH) and a weak acid (CH₃COOH).

CH3​COOH⟶CH3​COONa+H2​O

Sodium acetate which is formed in the reaction is basic in nature so the $pH$ 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.
