Potassium chromate is the inorganic compound with the formula K 2 CrO 4. This yellow solid is the potassium salt of the chromate anion. It is a common laboratory chemical, whereas sodium chromate is important industrially.
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Predominance diagram for chromate. In aqueous solution, chromate and dichromate anions exist in a chemical equilibrium.. 2 CrO 2− 4 + 2 H + ⇌ Cr 2 O 2− 7 + H 2 O. The predominance diagram shows that the position of the equilibrium depends on both pH and the analytical concentration of chromium.

Calcium chromate is an inorganic compound with the formula CaCrO 4, i.e. the chromate salt of calcium. It is a bright yellow solid which is normally found in the dihydrate form CaCrO 4 ·2H 2 O. A very rare anhydrous mineral form exists in nature, which is known as chromatite .
The solution reddens litmus and is an astringent. Aqueous solutions are dark violet and turns green when it is heated above 50 °C. [ 1 ] In addition to the dodecahydrate , the hexahydrate KCr(SO 4 ) 2 ·6H 2 O, dihydrate KCr(SO 4 ) 2 ·2H 2 O, and the monohydrate KCr(SO 4 ) 2 ·H 2 O are known.
Potassium dichromate, K 2 Cr 2 O 7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health.
