Because it was created by a strong base (NaOH) and a weak acid, CH3COONa is a basic salt (CH3COOH).
CH3COOH ⇆ CH3COONa + H2O
Because sodium acetate, which is generated during the process, is basic in nature, its pH is higher than 7.
For the culture of many essential bacteria, sodium acetate is commonly utilised as a carbon source.
During chrome tanning, this chemical is also utilized as a pickling agent.
A basic salt is a salt that is generated when a strong base is partially neutralised by a weak acid. They break down into a simple solution as they hydrolyze.
