The oxidation number of Ni in Ni(OH)2- is +2. This is because each hydroxide ion has a charge of -1, and the overall charge of the compound is -1. Therefore, the nickel ion must have a charge of +2 to balance the charge of the two hydroxide ions.
The oxidation number of nickel (Ni) in NiO2 is +4. Oxygen typically has an oxidation number of -2, so the total oxidation number of the compound is 0. Since there are two oxygen atoms in NiO2, the oxidation number of nickel must be +4 to balance out the charge.
To find the oxidation number for Ni (nickel), you look at the overall charge of the compound or ion it is a part of. For example, in NiCl2, each Cl has an oxidation number of -1, so the sum of the oxidation numbers must equal the overall charge of the compound. Therefore, as NiCl2 is neutral, the oxidation number of Ni must be +2.
O.S. of Ni = +2 O.S. of O = -2 O.N. of cpd = 0
The oxidation number for Ni in NiO2 is +4. Nickel is known to have variable oxidation states, and in this compound, it is bonded to two oxygen atoms which have an oxidation number of -2 each. The overall charge of the compound is neutral.
In Ni2O3, since oxygen has an oxidation number of -2 and there are three oxygen atoms, the total oxidation number contributed by oxygen is -6. Since the compound as a whole is neutral, the total oxidation number must be 0. Therefore, the oxidation number of nickel (Ni) in Ni2O3 is +3 to balance out the oxidation number from oxygen.
The oxidation number of nickel (Ni) in NiO2 is +4. Oxygen typically has an oxidation number of -2, so the total oxidation number of the compound is 0. Since there are two oxygen atoms in NiO2, the oxidation number of nickel must be +4 to balance out the charge.

The oxidation number for Ni in NiS (nickel sulfide) is +2, while the oxidation number for S (sulfur) is -2. This is because in a compound, the overall charge must be neutral.
The oxidation number of CO3 in NiCO3 is -2. In this compound, each oxygen atom has an oxidation number of -2, and since there are three oxygen atoms in CO3, the overall charge for the carbonate ion is -2. Therefore, the oxidation number of CO3 is -2 in NiCO3.
The solubility product constant (Ksp) for Ni(OH)2 is approximately 3.0 x 10^-16. This indicates the equilibrium between the dissolved nickel (II) ions and the undissolved nickel hydroxide solid.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
0 in elemental form, +2 in its compounds
The oxidation number of nickel in nickel nitrate is +2. In nickel nitrate, the nitrate ion has a charge of -1, and since the overall compound is neutral, the nickel ion must have an oxidation state of +2 to balance the charges.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
