-2 oxidation state
The oxidation state of oxygen in the hydroxide ion (OH-) is -2.
When copper combines with oxygen to form copper oxide, the copper ion has a +2 charge. This is because copper typically forms a 2+ oxidation state when it combines with oxygen in this compound.
In terms of ionic compounds an oxide contain the oxide ion (O2-) Which is a single oxygen atom with a 2- charge. A peroxide contains the peroxide ion (O22-) which is a particle of two oxygen atoms bonded together and has a 2- charge. Unlike most normal oxides, peroxides tend to be oxidizers or at the very least, unstable. A superoxide contains the superoxide ion (O2-) which consists of two oxygen atoms bonded together and has a 1- charge. This ion is even more strongly oxidizing than the peroxide ion. In covalent compounds oxides are substances that contain oxygen in the 2- oxidation state and not bonded ot other oxygen atoms. Peroxide contain a peroxide group (O2) in which each oxygen atom is bonded to the other oxygen an to another atom, typically carbon or hydrogen. IN this case oxygen is in the 1- oxidation state.
The oxidation state for the phosphate ion (PO4) is -3. This is because oxygen typically has an oxidation state of -2 and there are four oxygen atoms in the phosphate ion. The oxidation state of phosphorus in the phosphate ion is therefore calculated as +3 to balance out the -8 charge from the four oxygen atoms.
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
The oxidation state of oxygen in the hydroxide ion (OH-) is -2.
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).

FeO is iron(II) oxide, also known as ferrous oxide, where iron has a +2 oxidation state. Fe2O3 is iron(III) oxide, also known as ferric oxide, where iron has a +3 oxidation state. This means FeO has one iron atom for each oxygen atom, while Fe2O3 has two iron atoms for every three oxygen atoms.
O2- is the formula for oxide ion. The negative symbol indicates the presence of anions and 2 represents the oxidation state.
The oxidation state of chlorine in the ClO- ion is 1+
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-
