What is the chemical name of cobalt oxide using the stock system?
Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
What is the formula for cobalt oxide?
The molecular formula is CoO Cation is Co^2+^Anion is O^2-^or in other wordscobalt(II) oxide = CoO = Co2+ + O2-
How reactive is cobalt?
Cobalt is a moderately reactive metal, exhibiting reactivity towards oxygen in the air to form a thin layer of cobalt oxide on its surface. This oxide layer acts as a protective barrier against further oxidation. Cobalt also reacts with acids to form cobalt salts, such as cobalt chloride or cobalt sulfate. Overall, cobalt's reactivity is lower compared to highly reactive metals like sodium or potassium.
What does the roman number III indicate in cobalt III oxide indicate?
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.
Is cobalt oxide a base or a salt?
Cobalt oxide can refer toCobalt(II) oxide, CoOCobalt(III) oxide, Co2O3Cobalt(II,III) oxide, Co3O4.The three have different properties.
