The combustible material at the tip of a safety match stick is?

  • A.Manganese dioxide
  • B.Sulphur
  • C.Antimony sulphide
  • D.Phosphorus

Answer: C

The head of a safety match contains antimony trisulphide as the combustible material, with potassium chlorate as the oxidiser and glue to bind them.

The red phosphorus is on the striking surface of the box; friction converts a trace of it to white phosphorus, which ignites and sets off the head.
