Cobalt(III) oxide is a chemical compound with the formula Co2O3. It is a dark brown solid that is insoluble in water. It is used as a catalyst in chemical reactions and as a pigment in ceramics.
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.
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-
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.
Cobalt oxide can refer toCobalt(II) oxide, CoOCobalt(III) oxide, Co2O3Cobalt(II,III) oxide, Co3O4.The three have different properties.
Take into account that oxygen has a negative 2 charge (O-2) and there are 3 of them; therefore, to form this compound Cobalt must have a positive 3 charge (Co3+) because there are 2 of them. The name of this compound is Cobalt (III) oxide or Cobaltic oxide.
The chemical formula for cobalt oxide can vary depending on the oxidation state of cobalt. Two common forms are cobalt(II) oxide, which has the formula CoO, and cobalt(III) oxide, which has the formula Co2O3.
The ionic compound Co2O is called cobalt(II) oxide.
The formula for cobalt III nitride is CoN.
The formula for cobalt II oxide is CoO. It contains one cobalt ion with a +2 charge and one oxide ion with a -2 charge, resulting in a neutral compound.
