Explain the reaction of chlorine with hydrogen sulphide gas.

Explain the reaction of chlorine with hydrogen sulphide gas.

Answers

Kavungya
Procedure:
- A gas jar full of chlorine gas is inverted into another containing hydrogen sulphide gas.

Observations:
- Yellow deposits (of sulphur)
- Misty fumes (hydrogen chloride gas)

Explanations:
- Chlorine oxidizes hydrogen sulphide gas to sulphur solid, while itself is reduced to hydrogen chloride gas.

Conditions:
- At least one of the gases must be moist; they do not react with each other in absence of moisture.
Note:
- In absence of moisture both gases are still in molecular form and hence cannot react; water facilitates their ionization hence ability to react.
- If aqueous hydrogen sulphide is used, then sulphur forms as a yellow suspension on the acidic solution
