chromaatfamilie
Chromate family refers to a group of inorganic compounds that contain the chromate anion, CrO4^2-. This anion is tetrahedral in structure and features a central chromium atom bonded to four oxygen atoms. Chromates are typically yellow or orange in color. The most common chromate is potassium chromate, K2CrO4, which is a bright yellow crystalline solid. Sodium chromate, Na2CrO4, is also widely used.
Chromates are generally soluble in water, although their solubility varies with the cation. They are often
It is important to note that many chromate compounds are toxic and considered carcinogenic. Their use has
