No, actually Mercurochrome(C20H8Br2HgNa2O6) in not a chromate, and in fact it does not contain any chromium. It is actually an organic complex which contains mercury.
I think Potassium chromate is not used in medicines. However, Potassium dichromate is used in making a homeopathic medicine called Kali Bichromicum
Chromate salts are the salts containing the anion chromate (CrO4)2-.
This is the chromate anion. It is written CrO42- . It is tetrahedral in shape (like methane). It gives a yellow colour to salts that contain it such as K2CrO4.
The chromate ion is CrO42-
Stannic chromate = Tin(IV) chromate = Sn(CrO4)2
Silver Chromate Ag=Silver CrO4= Chromate(a polyatomic ion)
Cesium Chromate = Cs2CrO4
Barium Chromate = BaCrO4
No, Potassium chromate is a compound
This compound is beryllium chromate.
Silver(I) chromate = Ag2CrO4
