Characteristic
Sodium chromate is the inorganic compound with the formula Na2CrO4. It exists as a yellow hygroscopic solid, which can form tetra-, hexa-, and decahydrates. It is an intermediate in the extraction of chromium from its ores.
Chemical formula：Na2CrO4•4H2O
Molar mass： 234.03 g/mol
Appearance：yellow crystals
Density：2.73 g/cm3
Melting point：792 °C (1,458 °F; 1,065 K) (anhydrous)；20 °C (decahydrate)
Solubility in water：31.8 g/100 mL (0 °C);84.5 g/100 mL (25 °C);126.7 g/100 mL (100 °C)
Solubility：slightly soluble in ethanol
Solubility in methanol：0.344 g/100 mL (25 °C)
Magnetic susceptibility (χ)：+55.0·10−6 cm3/mol
Crystal structure：orthorhombic
Application
Sodium chromate tetrahydrate is used as a corrosion inhibitor, wood preservative and an auxiliary in textile industry. It serves as an oxidant, which is used to prepare carboxylic acids and ketones from primary and secondary alcohols respectively. Further, it is used as a starting material to prepare other chromium compounds and as a catalyst in organic synthesis especially pharmaceuticals and agro chemicals.
