Definition and reaction of ethanoic acid ?
Answers
Ethanoic acid (CH3COOH) belongs to the group of carboxylic acids and is commonly called as acetic acid. It is slightly heavier than water with a density of 1.05 g/cm3. After adding 5-8% of acetic acid in water it becomes vinegar and is mostly used as preservatives in pickles. Acetic acid is the common name for Ethanoic acid.
Reactions of ethanoic acids:
Esterification reaction:
When carboxylic acid and alcohol react, the product formed is known as an ester. Below is an example of the formation of an ester from the reaction of ethanoic acid with absolute ethanol in the presence of an acid as a catalyst.
CH3COOH + CH3CH2OH → CH3COOCH2CH3
(Ethanoic acid) (Ethanol) (Esters)
Esters have a sweet fruity smell. They are mainly used for making perfumes and synthetic flavoring agents. The reaction of esters with alkalis gives carboxylic acid salt and alcohol. This reaction is used in the making of soaps and the process is called as saponification reaction.
CH3COOC2H5 + NaOH → C2H5OH + CH3COONa

What is Ethanoic Acid?
Ethanoic acid (CH3COOH) belongs to the group of carboxylic acids and is commonly called as acetic acid. It is slightly heavier than water with a density of 1.05 g/cm3. After adding 5-8% of acetic acid in water it becomes vinegar and is mostly used as preservatives in pickles. Acetic acid is the common name for Ethanoic acid.
Reactions of ethanoic acids:
Esterification reaction:
• When carboxylic acid and alcohol react, the product formed is known as an ester. Below is an example of the formation of an ester from the reaction of ethanoic acid with absolute ethanol in the presence of an acid as a catalyst.
CH3COOH + CH3CH2OH → CH3COOCH2CH3
(Ethanoic acid) (Ethanol) (Esters)
• Esters have a sweet fruity smell. They are mainly used for making perfumes and synthetic flavoring agents. The reaction of esters with alkalis gives carboxylic acid salt and alcohol. This reaction is used in the making of soaps and the process is called as saponification reaction.
CH3COOC2H5 + NaOH → C2H5OH + CH3COONa
Reaction with a base:
• Ethanoic acid reacts with a base to give the salt and water just like other mineral acids.
Reaction with carbonates and hydrogen carbonates:
• Carbon dioxide, salt, and water are produced when ethanoic acid reacts with carbonates and hydrogen carbonates. Sodium acetate is usually produced as a salt when ethanoic acid reacts with sodium bicarbonate as shown in the reaction below:
CH3COOH + NaHCO3 → CH3COONa + H2O + CO2
