When a molecule dissociates in to ions , some ions take up more electrons they required , they are said to be in Oxidation state.
If another ion which have deficient electrons came near this ion , the electrons from first ion transferred to another ion.
Now the oxidation number -2 means it has two excess electrons and want to loose two electrons to get stability.

What is the oxidation number change for the iron atom in the reaction?
The oxidation number change for the iron atom in a reaction is from Fe^0 (elemental form) to Fe^2+ or Fe^3+ (ionic form). This represents an oxidation of the iron atom, as it loses electrons and increases its oxidation state.
What is the oxidation number of an atom with 12 protons?
The oxidation number of an atom with 12 protons is +2. This is because the number of protons in an atom determines its atomic number, which also corresponds to its charge in simple cationic compounds.
What is the oxidation number of C6H8O6?
The oxidation number of each carbon atom in C6H8O6 is +4. Each hydrogen atom has an oxidation number of +1, and each oxygen atom has an oxidation number of -2.
What is the oxidation number of CH3OH?
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
What is the oxidation number of a typical atom of calcium?
0 in elemental form, +2 in its compounds
What is the oxidation number of isopropyl alcohol?
The oxidation number of the carbon atom in isopropyl alcohol (C3H8O) is -2, and for the oxygen atom, it is -2. The hydrogen atoms each have an oxidation number of +1.
What is the oxidation number of acetate?
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.
What is the oxidation number for HCOO-?
The oxidation number for HCOO- is -1. This is because in the HCOO- ion, the total charge is -1 and each hydrogen atom has an oxidation number of +1, while the carbon atom has an oxidation number of +2 and the oxygen atoms each have an oxidation number of -2.
What is the oxidation number of N 2?
The oxidation number of N in N2 is 0 since it is in its elemental form. In a diatomic molecule like N2, each nitrogen atom has an oxidation number of 0.
What is the oxidation number of OH?
The oxidation number of hydroxide (OH-) is -1. This is because oxygen typically has an oxidation number of -2, and hydrogen has an oxidation number of +1. In this case, there is one oxygen atom and one hydrogen atom, resulting in an overall oxidation number of -1.
What is the oxidation number of Al2S3?
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
What is the oxidation number element of c2o4 2?
In the oxalate ion (C2O4^2-), each carbon atom has an oxidation number of +3, and each oxygen atom has an oxidation number of -2. The net charge of -2 on the ion results in an overall oxidation number of -2.
