Ethanoic acid also undergoes neutralization reaction in the same manner as that of any other acid. Acetic acid is the other name for ethanoic acid . A 5 - 8 % of ethanoic acid in water is called vinegar . Stearic acid is one of the fatty acids present in the soaps. Saponificarion is the reaction reverse to that of esterification. When 2 molecules of Ethanoic acid reacts with sodium carbonate it produces 2 molecules of sodium ethanoate 1 molecule of water and 1 molecule of carbon di oxide. All the carboxylic acids react with alcohols to give easters . So is the case with Ethanoic acid it reacts with ethanol to give ethyle ethnoate that is an ester and water. Such reactions are known as esterification. When any carboxylic acid reacts with an alcohol to form an ester is called the esterification reaction. Glacial acetic acid is the 100 % acetic acid obtained by first freezing pure ethanoic acid to get glacier like structure then it is melt to get obtain the glacial acetic acid. |
