Why is Na2CO3 used in esterification test?
Answer: Sodium carbonate solution is added to neutralise any acids and the stopper replaced. The acidic impurities and any salts formed have now been removed in the aqueous sodium carbonate solution, therefore there should be no carboxylic acid or sulfuric acid catalyst left in the ester layer.
The common name comes from the common yet essential use of the compound in baking as a leavening agent.
Typically when it reacts with an acidic material such as hydrogen phosphates, cream of tartar, juice of lemon, yoghurt, buttermilk, cocoa, and vinegar, it releases carbon dioxide.
What is the role of sodium hydrogen carbonate during esterification?
In order to isolate the ester product, the first step would be neutralizing the solution.
This can be done by adding sodium bicarbonate, which is a weak base.
Sodium carbonate reacts with the carboxylic acid as well as the acid catalyst, thus increasing the pH of the solution.
Do esters react with sodium carbonate?
CAUTION: The sodium carbonate will react vigorously with any sulfuric acid remining in the crude ester forming carbon dioxide, CO2.
Add the sodium carbonate solution dropwise to prevent the mixture from bubbling out of the test tube.
