Which of the following element is used to make matchsticks?
- Sulphur
- Phosphorous
- Both a and b
- Nitrogen
Hint:
The chemicals work when they receive heat due to friction.
The correct answer is: Both a and b
- The match head consists of antimony trisulfide, potassium chlorate, and white phosphorus.
- However, the use of white phosphorus is considered unsafe for users. Currently, matches only contain antimony trisulfide and potassium chlorate.
- The face of the matchbox contains red phosphorus and the head contains potassium chlorate.
