Search results for Zn(NO3)2 at Sigma-Aldrich. Which of the metals in Exercise 2 was the strongest oxidizing agent? The first step is to jot down the charges of the elements since it is an ionic bond. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. The three oxygen atoms have a combined oxidation of -6, corresponding to their electromagnetic charge and the lone nitrogen has a charge, or oxidation number, of +5. Well, the molecule,Cu(NO3)2, has no charge so its total oxidation number is 0 Nitrate ( NO3) is an ion with charge -1 From Cu(NO3)2 there are 2 nitrate ions, therefore 2 x -1 = -2 Since the total is 0, copper must have oxidation number of +2. This is because oxygen always has an oxidation number of -2. Zn = 0 to +2; Net Change = +2 Some N = +5 to +2; Net Change = -3.
