Turnbull's blue is ferrous ferricyanide, Fe3[Fe(CN)6]2
Be3(PO4)2--------------Beryllium phosphate
Fe3(PO4)2 Ferrous Phosphate or, the more modern name; Iron(II)phosphate
A cation is a positive ion and an anion is a negative ion. So the compound you are describing as an ionic one. For example, Cation + Anion --> Ionic Compound Fe3++ O2- --> Fe2O3
Brownish green
ferrous ions and Fe3+ is ferric ion
ferrous ions and Fe3+ is ferric ion
ferrous ions and Fe3+ is ferric ion
The chemical name is iron(III) sulfate. It is an ionic compound made up from the ions Fe3+ and SO4 2-. The three in brackets refer to the transition state of the iron cation.
Turnbull's blue is ferrous ferricyanide, Fe3[Fe(CN)6]2
Fe 3+andOH -form the ionic compoundFe(OH)3-------------------------ferric hydroxide, or the modern name, iron (III) hydroxide.
Be3(PO4)2--------------Beryllium phosphate
Ferrous oxide is non-stoichiometric because Fe2+ is readily oxidised to Fe3+. A lattice forms with some Fe3+ replacing Fe2+ (2 Fe3+ replace on average 3Fe2+ ) The lattice structure can accomodate a small degree of "distortion" and the net result is a compound sample with a composition Fe0.95O.
Fe2(SO4)3 is Iron (III) Sulfate. The cation is Fe3+ and the anion is SO42-
Fe3(PO4)2 Ferrous Phosphate or, the more modern name; Iron(II)phosphate
You most likely mean Fe3+. This is not a compound, it is a monotaomic ion of the element iron.Because it carries a positive charge it is not a substance in its own right but is a component of some ionic compounds.It is called the iron III ion.
Answer this question… Fe3+
