Potassium chromate, K 2 CrO 4, is a yellow crystalline substance, with a density of 2.732 g/cm 3 and a melting point of 968.3Â°C. It is readily soluble in water: 62.9 g at 20Â°C and 79.2 g at 100Â°C in 100 g of water.It is produced by the action of potassium hydroxide, KOH, on potassium dichromate, K 2 Cr 2 O 7.hromate. any salt or ester of chromic acid. Simple chromate salts contain the divalent ion, CrO 4 2-- , and are orange.
