Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
The roman number III indicates that the ion of cobalt present in this form of cobalt in the cobalt oxide is Co3+. Since cobalt also exists as a Co2+ form, these must be distinguished in some way. The standard is to use roman numerals to denote the charge. Both Cobalt (III) oxide and Cobalt (II) oxide still have the chemical formula of Co3O4.
Cobalt oxide can refer toCobalt(II) oxide, CoOCobalt(III) oxide, Co2O3Cobalt(II,III) oxide, Co3O4.The three have different properties.
Co2(CO3)3The chemical formula of cobalt(III) carbonate [not cobalt(111)] is Co2(CO3)3.
The molecular formula is CoO Cation is Co^2+^Anion is O^2-^or in other wordscobalt(II) oxide = CoO = Co2+ + O2-

Co2O3
Cobalt oxide can refer toCobalt(II) oxide, CoOCobalt(III) oxide, Co2O3Cobalt(II,III) oxide, Co3O4.The three have different properties.
TiCO3 is the chemical formula of titanium carbonate.
Co2(CO3)3The chemical formula of cobalt(III) carbonate [not cobalt(111)] is Co2(CO3)3.
Cobalt II Oxide
The formula for cobalt (II) oxide is CoO.
The molecular formula is CoO Cation is Co^2+^Anion is O^2-^or in other wordscobalt(II) oxide = CoO = Co2+ + O2-
Cobalt Oxide ie, CoO is stable at above 900°C. However, Co (cobalt) can have 2 valencies, either Co(II) or Co(III). When it is Co(II) its oxide can be written as CoO and when its in Co(III) form, the oxide will be Co3O4. The reaction of conversion from CoO to Co3O4 is given below: 3 CoO + 1/2 O2 Co3O4
Cobalt(II) carbonate
cobalt glass is glass containing cobalt oxide or cobaltous oxide as a colouring agent. These oxides give the glass a blue colouring.
