Question

list the conclusions you will draw while studying the following properties of ethanoic acid. (1) odour (2) solubility in water (3) effect on litmus paper (4) reaction with sodium hydrogen carbonate​

Answer 1

1)pungent smell,2)yes,3)blue litmus turns red

Answer 2

Ethanoic acid (CH3COOH)also known as the acetic acid has a carboxylic acid group(-COOH) as it's functional group.

(1) Pungent odour

(2)When dissolved in water acetic acid undergoes dissociation to form hydrogen ion.However it is a weak acid because it doesn't completely dissociate in aqueous Solution.

(3) Because of a release of a proton acetic acid as an acidic character. Therefore it turns blue litmus paper to red.

(4)On reaction with NaHCO3 it produce CO2(brisk effervescence) which turn lime water milky.(CaCO3)
