To a piece of charcoal, sulphuric acid is added. Then :
A.
there is no reaction
B.
water gas is formed
C.
$$S{O_2}$$ and $$C{O_2}$$ are evolved
D.
$$CO$$ and $$S{O_2}$$ are evolved
Answer :
$$S{O_2}$$ and $$C{O_2}$$ are evolved
Solution :
Charcoal is a pure form of carbon, its reaction with hot $$conc.\,{H_2}S{O_4}$$ is as follows :
$$C + 2{H_2}S{O_4} \to 2{H_2}O + 2S{O_2} + C{O_2}$$
