do esters react with sodium hydroxide
Which of the following is formed by the reaction of an ester and NaOH?
An ester and NaOH produce an acid and an ALCOHOL in a Saponification reaction.20 mar. 2017
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.
What happens when sodium hydroxide reacts with ethyl ethanoate?
The reaction of ethyl ethanoate with sodium hydroxide is also called saponification reaction.
In this reaction formation of a sodium salt of the carboxylic acid takes place ( soap).
Do esters react with bases?
Esters react in the presence of an acid or a base to give back the alcohol and carboxylic acid.
