Layman's explanation: In 1820, chromate of iron was discovered by Dr. Samuel Hibbert Ware of Edinburgh, Scotland in the Shetland Isles. Chromate exists in equilibrium with dichromate (Cr2O72-), which is a strong oxidizing agent. The brightly colored salts of chromate are used in pigments in paints. Lead chromate is red in color while Barium chromate is yellow. It is also used to treat aluminum in order to protect against corrosion and to prepare the surface for paint and adhesives.
