Potassium chromate is an inorganic compound with the chemical formula K2CrO4. It is a yellow crystalline powder and a potassium salt of chromic acid. It is used to identify chloride ions. The chromium in potassium chromate is hexavalent and is a first-level carcinogen. Inhalation or ingestion can cause cancer.
Density: 2.732g/cm3
Melting point: 971°C
Appearance: yellow crystalline powder
Solubility: soluble in water, insoluble in ethanol
In aqueous solution, potassium chromate dissociates into chromate ions (CrO42-, yellow), which form a balance with another dimerized dichromate ion (Cr2O72-, red). Adding acid will shift the reaction balance toward the dichromate ion, making the solution orange-red.
Used in the manufacture of metal rust inhibitors and chromates. Used as an oxidant and mordant for printing and dyeing. Used in inks, pigments, enamels, metal corrosion protection, etc. .
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep the container sealed. Store it separately from reducing agents, flammables, combustibles, etc. Do not store or transport it together with food, feed, etc.
