DOT Classification: 8; Label: Corrosive

Ammonium bisulfate Specification

Ammonium bisulfate, also known as ammonium hydrogen sulfate, is a white, crystalline solid when it is completely pure, with formula (NH₄)HSO₄. It is commonly collected as a byproduct of flue gas desulfurization, formed by partial neutralization of sulfuric acid (H₂SO₄) aerosols by gaseous ammonia, NH₃. Indeed, the solid material can collect on and foul solid surfaces in the flues. It is too acidic for most end uses, and is corrosive to the skin.
It react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
When heated to high temperatures, Ammonium hydrogen sulfate may release toxic sulfur oxide and nitrogen oxide fumes. Ammonium hydrogen sulfate is soluble in water. Ammonium hydrogen sulfate is a chemical catalyst, used in hair preparations.
