Question
How does matchstick burn ?
✓
Answer
The head of the safety match contains antimony trisulphide and potassium chlorate. The rubbing surface has powdered glass and a little red phosphorus. When the match is struck against the rubbing surface, some red phosphorus gets converted into white phosphorus This immediately reacts with potassium chlorate in the matchstick head to produce enough heat to ignite antimony trisulphide and start combustion.
