Question

Saloni took a piece of burning charcoal and collected the gas evolved in a test tube.
(a) How will she find the nature of the gas?
(b) Write down word equations of all the reactions taking place in this process.

Accepted Answer

a) Add a few drops of water in the test tube containing gas. Now, cover the test tube and shake it well. After shaking, test the solution with blue litmus and red litmus. It will turn blue litmus red. Thus, the gas is acidic in nature.

b) Charcoal reacts with oxygen to form carbon dioxide gas.
$\underset{(C a r b o n f r o m c h a r c o a l)}{C} + \underset{(O x y g e n)}{O_{2}} \to \underset{(C a r b o n d i o x i d e)}{C O_{2} ↑}$

Carbon dioxide reacts with water to form carbonic acid, which turns blue litmus paper red.
$\underset{(C a r b o n d i o x i d e)}{C O_{2}} + \underset{(W a t e r)}{H_{2} O} \to \underset{\begin{matrix} (C a r b o n i c a c i d) \\ (T u r n s b l u e l i t m u s r e d) \end{matrix}}{H_{2} C O_{3}}$
