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
A red colour of cobalt chloride confirms the reaction is being occur.
Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
cobalt glass is glass containing cobalt oxide or cobaltous oxide as a colouring agent. These oxides give the glass a blue colouring.
sodium oxide + hydrochloric acid -> sodium chloride + hydrogen
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.
Hi
Cobalt II Oxide
Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
The formula for cobalt (II) oxide is CoO.
yes dilute hydrochloric oxide is a strong acid

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.
Cobalt Green, a pigment.
Yes copper oxide reacts with hydrochloric acid and it forms a blue green compound.
