Why is NaCl added to soap? - FindAnyAnswer

Why is NaCl added to soap? The addition of salt (sodium chloride) to the crude form of soap forms fatty-acid salts. The sodium ions from the sodium chloride bond with the fatty acid, forming a product that is less soluble in water. Because of this reduced solubility, the soap leaves the solution and forms a solid mass.

The aqueuos phase will become very acidic (phosphoric acid and HBr) and some of this acidity transfers to the aqueous phase. The washing with bicarbonate will then remove the acid from the aqueous phase. It will also remove traces of bromine (slight yellow colour) in the product as well. Bromine can be a by-product of the reaction.
