natriumchromaat
Natriumchromaat, or sodium chromate, is an inorganic salt with the chemical formula Na2CrO4. It consists of two sodium ions and the chromate anion CrO4^2−, in which chromium is in the +6 oxidation state. The solid is typically yellow and crystalline, highly soluble in water, and forms basic chromate salts in alkaline conditions.
Industrial production of sodium chromate is usually by oxidation of sodium dichromate in alkaline media or
Applications of sodium chromate include its use as an oxidizing agent in organic synthesis, as a pigment
Safety and environmental notes are important for sodium chromate. Hexavalent chromium compounds are toxic and carcinogenic,
