Explanation:
Litmus Test:
A litmus test is used to determine if a solution is acidic or basic.
Blue litmus paper turns red in acidic conditions.
Red litmus paper turns blue in basic or alkaline conditions.
Litmus test of the compound X:
Ethanoic acid is acidic in nature, since the compound X turns blue litmus red thus, it must be acidic in nature.
The molecular formula, defines that the compound is ethanoic acid
.
Reaction of Ethanoic acid with Sodium bicarbonate:
Ethanoic acid
or reacts with sodium bicarbonate
and gives carbon dioxide
gas (evolves with brisk effervescence) along with sodium acetate
, and water
.
The chemical reaction is as follows
The gas evolved in the above reaction is carbon dioxide
.
So, from the above reaction, it can be said that the organic compound X is Ethanoic acid
that turns blue litmus red and produces brisk effervescence with sodium bicarbonate.
