Oxidation number: Zn= 0 [Cu]SO4 = +2 [Zn]SO4 = +2. We know that the compound CuSO 4 has an overall charge of 0 (neutral). - the question states assign oxidation numbers to the element in the following compounds 1. 0 0. Solution for Match the oxidation number for sulfur with each of the molecular formulas that contain sulfur. You wrote that its total charge was #-2#.. Relevance. 1 Answer The oxidation number of a free element is always 0. 0 v H2S C. +2 S8 D. +6 Na2SO3 E. -2… Therefore, we can set up a mathematical equati on to solve for the overall charge (oxidation number) on Cu. Copper can also have oxidation numbers of +3 and +4.. ON = +2: Examples are CuCl₂, CuO, and CuSO₄.See, for example Source(s): self. Example: Determine the oxidation number on Cu in CuSO 4. conclusion: oxidation number for some elements can differ from one compound to another. to balance that Cu has to have a +2 charge. For MgH2 the oxidation number of Mg is +2 [because group 2 metals are always +2] so the oxidation number of H is -1. Using the relation, Let the oxidation number of sulphur be x. the sulfate ion has a -2 charge. If the Cu is +2 and the four O's are each -2, the net result for S is +6. The oxidation number of the sulfur atom in the SO 4 2-ion must be +6, for example, because the sum of the oxidation numbers of the atoms in this ion must equal -2.
