Explain the reaction of chlorine with hydrogen.

Explain the reaction of chlorine with hydrogen.

Answers

(i). Conditions:
- Heating or presence of light; since chlorine and hydrogen do not react with each other at room temperature.

(ii). Precaution:
- The experiment is performed in a fume chamber (cupboard); since the reaction is explosive;

(iii). Procedure:
- Chlorine gas is mixed with hydrogen gas and the mixture heated or exposed to direct light; then aqueous ammonia brought near the mouth of the jar.

(iv). Observations:
- White fumes at the mouth of the jar.

(v). Explanations:
- Chlorine reacts explosively with hydrogen to form hydrogen chloride gas.



- The hydrogen chloride gas diffuses upwards and reacts with ammonia at the mouth of the test tube to form white fumes of ammonium chloride; NH₄Cl.
