2. WHAT IS ETHANOIC ACID? Ethanoic acid is commonly called as acetic acid and it belongs to a group of acid called carboxylic acid.

3. PROPERTIES OF ETHANOIC ACID 5-8% of solution of acetic acid in water is called vinegar and it is used widely as a preservative in pickles. The melting point of pure ethanoic acid is 290K and it gets freezes during winter in cold climates. Due to which it also get name as glacial acetic acid. This compound mostly used in antacids .

4. REACTIONS OF ETHANOIC ACID Esterification Reaction: Esters are most commonly formed by reaction of an acid and an alcohol. Ethanoic acid reacts with absolute ethanol in the presence of an acid catalyst to give an ester- CH 3 COOH + CH 3 CH 2 OH ACID CH 3 C O CH 2 CH 3 (EHANOIC ACID) (ETHANOL) (ESTER) Esters are sweet-smelling substance. This are used in making perfumes and as flavoring agents. On treating with sodium hydroxide, which is an alkali the ester is converted back to alcohol and sodium salt of carboxylic acid. This reaction is knows as saponification reaction because it is used in preparation of soap. CH 3 COOC 2 H 5 NaOH C 2 H 5 OH+CH 3 COONa Ethanoic acid reacts with a base such as sodium hydroxide to give a salt and water. Ethanoic acid reacts with carbonates and hydrogencarbonates to give rise salt, carbon dioxide and water. The salt produced is commonly called as sodium acetate.
