View HintsHard water doesnt produce that much of lather with soap as hard water reacts with soap to form curdy white precipitate. In short ethyle ethanoate can be written as C4H8O2. Water is hard due to the presence of calcium and magnesium ions. When a molecule of Ethanoic acid reacts with sodium hydrogen carbonate it produces a molecule of sodium ethanoate 1 molecule of water and 1 molecule of carbon di oxide. When an ester is heated with dilute sodium hydroxide it changes back into the original alcohol and sodium salt of the original carboxylic acid . Such reaction is known as saponification. Ethanoic acid also undergoes neutralization reaction in the same manner as that of any other acid. Water loving part of soaps and detergents is called hydrophilic and the dirt loving part is called hydrophobic part. When any carboxylic acid reacts with an alcohol to form an ester is called the esterification reaction. Water loving part of soaps and detergents is called hydrophilic and the dirt loving part is called hydrophobic part. 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. |
