Iron(III) chromate is the iron(III) salt of chromic acid with the chemical formula Fe2(CrO4)3.
Discovery
Iron(III) chromate was discovered by Samuel Hibbert-Ware in 1817 while visiting Shetland.[2]
Production
It may be formed by the salt metathesis reaction of potassium chromate and iron(III) nitrate, which gives potassium nitrate as byproduct.
- 2 Fe(NO3)3 + 3 K2CrO4 → Fe2(CrO4)3 + 6 KNO3
It also can be formed by the oxidation by air of iron and chromium oxides in a basic environment:
- 4 Fe2O3 + 6 Cr2O3 + 9 O2 → 4 Fe2(CrO4)3
