Cobalt oxide can refer to
It's a salt. When most metals combine with a halogen, it is considered a salt. Cobalt is a transition metal and chlorine is a halogen.
cobalt (ii) carbonate is a weak base
Acid
Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
It is a SALT.
NO!!! It is a chemical Salt. Calcium Oxide is a base.
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.
Cobalt II Oxide
Cobalt oxides are: cobalt(I) oxide, cobalt(II) oxide and cobalt(II,III) oxide.
It is a SALT.
The formula for cobalt (II) oxide is CoO.
NO!!! It is a chemical Salt. Calcium Oxide is a base.
It is a simple metal oxide, which can make it a salt.
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.
The products are a salt and water.
It is an AMPHOTERIC oxide. That is , in an environment of low(acid) pH it behaves as a BASE. In an environment of high(alkaline) pH it behaves as an 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.
