Question

Sugar charcoal is obtained by adding concentrated to cane sugar.

• A. sulphuric acid
• B. sodium hydroxide
• C. hydrochloric acid

Answer 1

The correct option is A sulphuric acid

Sugar charcoal is a type of plant charcoal, obtained from cane sugar. It can be obtained by destructive distillation of cane sugar or by adding concentrated sulphuric acid $\left(H_{2}S{O}_4\right)$ to cane sugar.

Conc. $H_{2}S{O}_4$ is used because it is a strong dehydrating agent and absorbs water from the cane sugar leaving behind pure carbon i.e. charcoal.
