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.
Can be purchased from chemical suppliers.
- Make chromium(III) oxide
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, with a proper label and a hazard symbol. As it gives off ammonia over time, the bottle should be open periodically.
Ammonium chromate can be neutralized with a reducing agent, such as ascorbic acid or sodium/potassium sulfite/metabisulfite/thiosulfate.
