Question

if a colourless gas is evolved with smell of vinegar while adding dil.H2SO4 in the salt , we say that acetate radical is present in it. What is the that colourless gas evolved please explain with a chemical equation. need the answer asap!!

Answer 1

We know that the chemical name of vinegar is ethanoic acid which is also called acetic acid.

Chemical formula of ethanoic acid (or vinegar ) is $CH_{3}COOH$.

So,when it reacts with any salt, the colourless gas called carbon dioxide ( $CO_{2}$ ) is evolved.

Example :

Let's suppose that salt is sodium bicarbonate ( $NaHCO_{3}$ )

$CH_{3}COOH$  +  $NaHCO _{3}$  
                                    
                                       ⇒ $CH _{3}COONa + H _{2}O + CO_{2}$
