Question

Phosphorus is widely used in the match industry due to its low ignition temperature.
A. True
B. False

Answer 1

Hint: For solving this question, we need to study the concepts and uses of phosphorus. We all need to know that the tip of the matchstick contains phosphorus sesquisulfide. The chemical formula is ${P_4}{S_3}$. It is a non-toxic, stable compound, which is converted to flammable white phosphorus when the match-head is struck across a rough surface.

Complete step by step answer:
When the match is struck, a small amount of the red phosphorus on the striking surface is converted into white phosphorus, which then ignites. The heat from this ignites the potassium chlorate, and the match head bursts into flame.
We have to remember that the red phosphorus replaced white phosphorus in matches because it was much more stable. It is contained in the striking surface of safety matches, not in the match head. We have to remember that the tip of a matchstick contains potassium chlorate. When we rub the matchstick, white phosphorus is produced from the red phosphors.
We have to remember that the red phosphorus (allotrope of phosphorus) is used to make matchsticks as it burns readily. So, it is used in the match industry due to its low ignition temperature property.

Hence, the statement is true.

Note: After solving this question, we need to know about the different uses of Phosphorus. Phosphorus is used in the manufacture of safety matches, pyrotechnics and incendiary shells. It is also used in steel manufacturing industries and in the production of phosphor bronze. Phosphates are ingredients that are used in detergents. Also, it is used to make light-emitting diodes (LEDs). In the largest form, it is used for fertilizers. Ammonium phosphate is made from phosphate ores. We have to remember that the red phosphorus and white phosphorus are the allotropes of phosphorus.
