Calcium carbonate precipitates as a solid, leaving ammonium sulfate in the solution. (NH 4) 2 CO 3 + CaSO 4 → (NH 4) 2 SO 4 + CaCO 3. Ammonium sulfate occurs naturally as the rare mineral mascagnite in volcanic fumaroles and due to coal fires on some dumps. [14] Ammonium sulfate is a byproduct in the production of methyl methacrylate. [15]
ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulfate, the former being the active component. The mix between the two agents is usually 40–60%, 60–40%, or 90–10% depending on local standards worldwide. The USGS uses a similar mixture, called Phos Chek G75F. [2]
The cause of the explosion was the ignition of ammonium nitrate used as raw material for fertilizer and explosives. [citation needed] Australia Taroom, Queensland 30 August 1972: 3 12 In the 1972 Taroom explosion, a truck carrying 12 tons of ammonium nitrate experienced an electrical fault and caught fire north of Taroom, Queensland. After the ...
This highly dangerous procedure was in fact common practice. It was well known that ammonium nitrate was explosive, having been used extensively for this purpose during World War I, but tests conducted in 1919 had suggested that mixtures of ammonium sulfate and nitrate containing less than 60% nitrate would not explode. On these grounds, the ...
The devastating explosion in Beirut should be a wake-up call for countries on the dangers of ammonium nitrate, which caused the blast, experts say. Lebanese authorities said 2,750 tonnes of the ...
Ammonium iron(III) sulfate, NH 4 Fe(SO 4) 2 ·12 H 2 O, or NH 4 [Fe(H 2 O) 6](SO 4) 2 ·6 H 2 O, also known as ferric ammonium sulfate (FAS) or iron alum, is a double salt in the class of alums, which consists of compounds with the general formula AB(SO 4) 2 · 12 H 2 O. [2] It has the appearance of weakly violet, octahedrical crystals.
Ammonium sulfamate (like other ammonium salts, e.g. Ammonium dihydrogen phosphate, Ammonium sulfate) is a useful flame retardant. [4] These salt based flame retardants offer advantages over other metal/mineral-based flame retardants in that they are water processable.
Conventional shampoos often contain harsh detergents such as sodium lauryl sulfate (SLS) and ammonium lauryl sulfate (ALS). These detergents strip the hair of its natural oils and cause damage to ...
