Ammonium sulfate | (NH4)2SO4 - PubChem

Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280degreeC) white solid which is very soluble in water (70.6 g/100 g water at 0degreeC; 103.8 g/100 g water at 100degreeC), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.
