Oxygen pretty much always has an oxidation number of -2 (there are few exceptions.) A better question is "What is arsenic's oxidation number in this ion?" It would be +5.
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
Usually the oxidation no of oxygen is -2 and the oxidation no of hydrogen is +1 in a compound.
The oxidation number of oxygen in OF2 is 2.
The oxidation state of oxygen in the compound is -2.
The oxidation number of oxygen in OF2 is +2. Oxygen usually has an oxidation number of -2, but in this case, since there are two fluorine atoms each with an oxidation number of -1, the oxidation number of oxygen must be +2 to balance the overall charge.
The oxidation number of oxygen is -2 in most of its compounds

Oxidation state of Oxygen in:Peroxides is -1Superoxides is - 1/2

The oxidation state for oxygen in the oxide ion (O2-) is -2. Oxygen typically has an oxidation state of -2 in most of its compounds.
The oxidation number of oxygen when combined with fluorine is -1. Oxygen usually has an oxidation number of -2, but when combined with a more electronegative element like fluorine, oxygen's oxidation number becomes -1.
the most common oxidation number for oxygen is -2.
Removing oxygen does prevent oxidation from occurring since oxidation is a chemical reaction that involves the gain of oxygen by a substance. Without oxygen present, oxidation cannot take place.
