It depends on whether O2 is present. If not the formula would be Fe(II)tannate, if oxygen is present it would be Fe(III)tannate because air readilly oxidizes Fe(II) to Fe(III).
The formula for Iron II iodate is Fe(IO3)2. Iron II iodate is an inorganic compound.
Iron III = Fe^+3 and hydrogen sulfate = HSO4^-1, therefore Iron (III) Hydrogen Sulfate = Fe(HSO4)3
Fe2+
The chemical formula for copper (I) iodide is CuI, and for copper (II) iodide is CuI2. Copper (I) iodide is the more common of the two.
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
Probably manganese iodate: Mn(IO3)
The formula for iron(II) flluoride is FeF2. The formula for iron (III) fluroide is FeF3.
The platinum(II) cation has a 2+ charge, with the formula Pt^2+. The iodate anion has a 1- charge, with the formula IO3^1-. The formula of platinum(II) iodate must be neutral, so one platinum(II) cation and two iodate anions must combine to form Pt(IO3)2.
manganese(II) iodate is Mn(IO3)2
The chemical formula for copper (I) iodide is CuI, and for copper (II) iodide is CuI2. Copper (I) iodide is the more common of the two.
The formula for Iron(II) sulfate is FeSO4.
Iron (II) hydride has the formula FeH2.
Sodium iodate is NaIO3.
molecular formula for iodate is IO3-
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
IRON iODATE
The chemical formula of iron(II) phosphate is Fe3(PO4)2.
The chemical formula of iron(II) phosphate is Fe3(PO4)2.
Probably manganese iodate: Mn(IO3)
The formula for iron(II) flluoride is FeF2. The formula for iron (III) fluroide is FeF3.
