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 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

Ammonium sulfate is NH4 + SO4, so not only will the sulfate make sulfuric acid, but the NH4 (ammonium) will break down to NO3 (nitrate) and release extra H+ into the soil, which makes the soil more acid. Same thing with epsom salts. Mg + SO4. Sulfate when added to water takes the hydrogen out of water and makes an acid.

The other sulfate salts (ammonium, magnesium, sodium, potassium) react with calcium hydroxide (portlandite) in the concrete to form calcium sulfate (gypsum) as shown below. This calcium sulfate may then interact with the calcium aluminate phase to form ettringite, as in the reaction detailed above (St John et al., 1998).

leaching treatment with gypsum. Topdress 1 tablespoon of gypsum (calcium sulfate) to each 6-inch pot and water in thoroughly with clear water. Follow with a 50 parts per million drench of calcium nitrate two hours later. The ammonium bonds with the sulfate from the gypsum and becomes highly soluble allowing it to flush easily out of the medium.

Gypsum | Minerals Education Coalition

In all, more than 90 countries produce gypsum. In most open pit gypsum operations, benches are drilled and blasted using ammonium nitrate as the explosive. Because gypsum is so soft, most drills can drill through it at a rate of roughly 23 ft per minute. Sometimes the drill holes become wet, which can cause problems with the ammonium nitrate.
