Question

Explain the destructive distillation of Coal.

Answer 1

1. The destructive distillation of coal can be carried out in the laboratories.
2. Finely powdered coal is taken in a test tube and heated.

1. At a particular temperature, coal breaks down to produce coke, coal tar, ammonia, and coal gas.
2. Coal tar is deposited at the bottom of the second test tube and coal gas escapes out through the side tube.
3. Ammonia produced is absorbed in the water, forming ammonium hydroxide.
4. Finally, a black residue called coke is left in the first tube.
