What are the chemicals present in match stick?

  By GK Planet Team       Monday, 12 February 2018
Q. What are the chemicals present in matchstick?

A. Red phosphorous, glue, sulphur
B. Antimony Sulphide, sulphur, potassium chlorate
C. Antimony -sulphide, red phosphorous, glue
D. Antimony sulphide, phosphorous, sulphür

Answer: Antimony Sulphide, sulphur, potassium chlorate

Chemical Used in Matchstick & Match Box

Tip of Match has potassium chlorate (an oxidant), sulfur, starch, glue and some other ingredients.

Striking Surface has red phosphorus, powdered glass, and glue.

Safety matches ignite due to the extreme reactivity of phosphorus with the potassium chlorate in the match head. When the match is struck the phosphorus and chlorate mix in a small amount forming something akin to the explosive Armstrong's mixture which ignites due to the friction.
