Physical Description
Ammonium chromate appears as a yellow crystalline solid. Density 1.866 g / cm3. Soluble in water. Toxic by inhalation (of dust). A strong irritant. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Used in dyeing, photography, chemical analysis, and as a corrosion inhibitor.
