Question

The head of a safety match contains-

• A. Antimony trisulphide and potassium chlorate
• B. Antimony chloride and potassium sulphide
• C. Antimony carbonate
• D. Potassium sulphide

Answer 1

The correct option is A

Antimony trisulphide and potassium chlorate

Explanation:

1: The head of a matchstick is used for the generation of heat by striking it on the surface of the matchbox. In this way, the head of the matchstick is ignited due to the caused friction.

2: The head of the matchstick consists of Antimony trisulphide (${\mathrm{Sb}}_2{\mathrm{S}}_3$) and Potassium chlorate (${\mathrm{KClO}}_3$) whereas the rubbing surface of the matchbox possesses powdered glass and red phosphorus on it. The union of all these components leads to the generation of heat.

Thus, the head of a safety match possesses antimony trisulphide and potassium chlorate.

Final answer:

Hence, option (A) is correct.
