Shannon Brown on 03 Jun 12Gunpowder or black powder is of great historical importance in chemistry. Although it can explode, its principal use is as a propellant. Gunpowder was invented by Chinese alchemists in the 9th century. Originally, it was made by mixing elemental sulfur, charcoal, and saltpeter (potassium nitrate).
