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 naturally 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.
Ammonium chloride will react with sodium hydroxide to give off ammonia gas.
Ammonium chloride is a white crystalline solid, soluble in water.
Ammonium chloride can be found in many electronic stores, as soldering iron flux. It can also be found in some chimney cleaning products, where it tends to be mixed with other compounds, such as ammonium sulfate. Crystallization or sublimation can be used to extract and purify the compound.
Ammonium chloride is sold by various chemical suppliers.
- NH3 + HCl → NH4Cl
If the reaction occurs in gaseous phase, a very fine mist of ammonium chloride will form.
- Growing crystals
- Making smoke bombs
Inhalation: Irritating to mucous membranes. Irritating to respiratory system.
Skin exposure: Repeated or prolonged exposure may cause dermatitis
Ingestion: Harmful if swallowed in large dosages. May cause nausea, vomiting and acidosis. In small dosages it can be consumed without ill effects.
Eyes contact: Irritating to eyes.
Store in a cool, dry, well ventilated place, in securely closed original container.
Ammonium chloride solution could be poured down the drain or disposed in envniroment as fertilizer (In small quantities).
