Sodium chromate is an inorganic compound with the chemical formula Na2CrO4. It appears as a yellow crystalline solid and is primarily used in various industrial applications, including the production of pigments, corrosion inhibitors, and in the manufacturing of glass. Sodium chromate is soluble in water and can be hazardous due to its chromium content, which is toxic and can pose environmental risks. In addition to its industrial uses, sodium chromate plays a role in analytical chemistry as a reagent. It is also involved in the process of chromate conversion, which helps protect metals from corrosion. Proper handling and disposal are essential to minimize its environmental impact and health risks.
