Product Description:
Potassium chromate is the inorganic compound with the formula (K2CrO4).
This yellow solid is the potassium
salt of the chromate anion. It is a common
laboratory chemical, whereas sodium chromate is important industrially.It is a
class two carcinogen.
[Applications]
Unlike the less expensive sodium salt, potassium salt is mainly used for laboratory work in situations where an anhydrous salt is required.
It is as an oxidizing agent in organic synthesis. It is used as in qualitative inorganic analysis, e.g. as a colorimetric test for silver ion.
