MCQ
When Conc. $H_2SO_4$ is added to charcoal :-
  • A
    There is no reaction
  • B
    Water gas is formed
  • ✓
    $SO_2$ and $CO_2$ are evolved
  • D
    $CO$ and $SO_2$ are evolved
✓

Answer

Correct option: C.
$SO_2$ and $CO_2$ are evolved
c
To a piece of charcoal sulfuric acid is added. Then $\mathrm{CO}_{2}$ and $\mathrm{SO}_{2}$ are evolved.

$\mathrm{C}+2 \mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{CO}_{2} \uparrow+2 \mathrm{SO}_{2} \uparrow+2 \mathrm{H}_{2} \mathrm{O}$

$\mathrm{H}_{2} \mathrm{SO}_{4}$ is reduced to $\mathrm{SO}_{2}$ and $\mathrm{C}$ is oxidised to $\mathrm{CO}_{2}$
