Ammonium sulfate - WikipediaJump to Preparation - Preparation. Ammonium sulfate is made by treating ammonia, often as a by-product from coke ovens, with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SOAmmonium sulfate ([NH4]2SO4) - Cold Spring Harbor ProtocolsAmmonium sulfate ([NH4]2SO4). To prepare a 1 M solution, dissolve 1.3 g of solid (NH4)2SO4 in a final volume of 10 mL of H2O.
