Iron(III) chromate is the iron(III) salt of chromic acid with the chemical formula Fe2(CrO4)3.

Discovery

[edit]

Iron(III) chromate was discovered by Samuel Hibbert-Ware in 1817 while visiting Shetland.[2]

Production

[edit]

It may be formed by the reaction of potassium chromate and iron(III) nitrate. This reaction forms iron(III) chromate and potassium nitrate. 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

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
