Cobalt Green, a pigment.
Cobalt II Oxide
Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
calcium chloride
The formula for cobalt (II) oxide is CoO.
many, zinc oxide, zinc carbonate, zinc chloride...
cobalt glass is glass containing cobalt oxide or cobaltous oxide as a colouring agent. These oxides give the glass a blue colouring.
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.
Sodium chloride solution is corrossive for aluminium; first a layer of of aluminium oxide is formed.
Lithium oxide - Li2O Three oxides of lithium are known: Li2O, Li2O2, LiO2.
Cobalt oxide can refer toCobalt(II) oxide, CoOCobalt(III) oxide, Co2O3Cobalt(II,III) oxide, Co3O4.The three have different properties.
Cobalt oxide can be reduced by hydrogen to form cobalt metal. Manganese dioxide can be reduced by hydrogen to form manganese metal. Magnesium oxide cannot be reduced by hydrogen. Calcium oxide cannot be reduced by hydrogen.
It changes color for Purple to Blue if it was heated and if it was cooled down then it will change color from purple to pink
