Ammonium chloride is an inorganic compound with the formula NH4Cl. It's white crystalline solid, highly soluble in water.Solutions of ammonium chloride are mildly acidic. Ammonium chloride occurs naturaly as mineral Sal ammoniac which is commonly formed on burning coal dumps, due to condensation of coal-derived gases. It is also found around some types of volcanic vents. Ammonium chloride is mainly used as fertilizer and as flavouring agent in some types of liquorice.
Contents
Properties
Chemical
Ammonium chloride will react with sodium hydroxide to give off ammonia gas.
Physical
Ammonium chloride is a white crystalline solid, soluble in water.
Availability
Ammonium chloride is sold by various chemical suppliers.
Preparation
Reaction of hydrochloric acid with ammonia will result in ammonium chloride.
- NH3 + HCl → NH4Cl
If the reaction occurs in gaseous phase, a very fine mist of ammonium chloride will form.
Projects
- Growing crystals
- Making smoke bombs
