Ammonium chromate is a salt with the formula (NH4)2CrO4.
Ammonium chromate, like ammonium dichromate burns when ignited, creating a volcano-like effect.
Ammonium chromate is a yellow solid, soluble in water, sparingly soluble in organic solvents.

Ammonium chromate is flammable and extremely toxic. It is a known carcinogen. Wear proper protection, such as gloves and a mask.
Ammonium chromate should be stored in closed bottles, in well ventilated places. As it gives off ammonia over time, the bottle should be open periodically.
