Question

how ethanoic acid is prepared

Answer 1

Answer:

Oxidation with dichromate under reflux, or in the case of nitrile, acid hydrolysis.

Explanation:

Ethanol can be refluxed with excess of potassium dichromate solution (oxidising agent) and dilute sulphuric acid (catalyst). You need to reflux because the ethanol will initially form acetaldehyde and you need to prevent this from volatilising away before it is fully oxidised to acetic acid, which can then be distilled off.

You can convert acetonitrile (ethanenitrile) to acetic acid by acid hydrolysis - reflux the nitrile with dilute hydrochloric acid, and you will form the acetic acid which can then be distilled off

Answer 2

ethanoic acid is also known as formic acid is a weak acid is a a weak Acid which is a natural acid and present in vinegar when be added ethanoic acid with ethanol it prepared Easter which have a sweet smell and this process is known as is esterification so the ethanol ethanoic acid is mainly used in esterification it is a transparent liquid.
