Q 01) What is the advantage of Sodium Carbonate solution? Q 02) : Does the whole liquid mixture in sodium carbonate mixture is called Ester or do we have to filter it or do some other activity also to separate the ester ?

no, you cannot as esterification is a reversible reaction, heating it with high heat can cause the decomposition of the ester to form back your alcohol and your carboxylic acid.
