The bicarbonate washings of the ester product are followed by a single 20-mL wash using distilled water to remove any bicarbonate ions that may still be mixed with product. After the water layer (bottom layer) is removed, the isopentyl acetate is transferred to an 100-mL round bottom flask (use 19/22 ground glass flask).

Now, in this reaction, we still has traces of HBr in the product, so, in order to neutralize these traces, we wash the solution with bicarbonate sodium forming sodium bromide and carbonic acid as follow: HBr + Na2CO3 ---------> NaBr + Na2CO3 Also, this is a weak base so it will not react with the n-butylbromide to form another product.

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.
