Flammable; heat produces toxic nitrogen oxides, sulfur oxides and ammonia fumes

May explode if mixed with oxidizers, such as potassium nitrate, potassium nitrite and potassium chlorate.

Odorless

pH = 5.5 (0.1 M aqueous solution)

Average specific heat capacity: 1.423 J/g-K at 2-55 °C; heat of solution on dissolution of 1 mol in 400 mol water: +9.92 kJ at 18 °C; integral heat of solution: +6.57 kJ/mol at 30 °C; differential heat of solution for saturated solution: +6.07 kJ/mol at 30 °C; deliquesces above 80% relative humidity|Decomposes above 280 °C

Dissolves in water with evolution of some heat.

Salts, Acidic

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].

Not flammable (USCG, 1999)

Does not attack iron or aluminum /Ammoniacal solutions/
