what is the chemical properties of ethanoic acid?

1.

Reaction with alcohol or esterification reaction: The reaction of a carboxylic acid with an alcohol to form an ester is known as esterification reaction.


 

When ethanoic acid reacts with ethanol in the presence of an acid, ethyl ethanoate is formed.

Esters react in the presence of an acid or a base to give back alcohol and carboxylic acid as follows:

This reaction is used in the preparation of soaps and is known as saponification reaction.


2. Reaction with a base:

We know that an acid and a base react to form salt and water. Similarly, ethanoic acid reacts with sodium hydroxide to form a salt, sodium ethanoate, and water. Sodium ethanoate is commonly known as sodium acetate.

3. Reaction with carbonates and hydrogen carbonate:

Carbonates and bicarbonates are also basic in nature and react with ethanoic acid to form salt and water. Carbon dioxide is also formed in the reaction. The chemical equations involved are given as:

Sodium ethanoate is produced in the reaction. It is commonly known as sodium acetate.

Acidity

The hydrogen center in the carboxyl group (−COOH) in carboxylic acids such as acetic acid can separate from the molecule by ionization:

CH3CO2H → CH3CO2- + H+

Organic chemistry

Two typical organic reactions of acetic acid

Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetateand water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH2CO2Li. Reduction of acetic acid gives ethanol.

The common name of ethenoic acid is acetic acid.It is the second member of the homologous series of carbaxylic acid;the first member being methanoic acid.5-8% of acetic acid in water is called vinegar and are used widely as a preservative in sausages,pickles,etc...

  1. it turns blue litmus red
  2. it reacts with sodium carbonate to form sodium ethanoate(CH3COONa) and CO2
  3. it reacts with sodium hydrogencarbonate to form sodium ethanote, water and CO2 with brisk effervescence
  4. it reacts with sodium hydroxide to form sodium ethanote, water
  5. it reacts with ethanol to form ester and water
