Ammonium sulfate Chemical Properties,Usage,Production

Chemical Properties White crystalline powder Usage May be used for the precipitation or fractionation of proteins or for purification of antibodies. Useful for crystallographic analysis of nucleic acids and proteins. General Description White odorless solid. Sinks and dissolves in water. Air & Water Reactions Dissolves in water with evolution of some heat. Reactivity Profile Ammonium sulfate is acidic in aqueous solution. When a little Ammonium sulfate is added to fused potassium nitrite, a vigorous reaction occurs attended by flame [Mellor 2:702 1946-47].
