(Copper Sulfate)? we know there is sulphuric acid (H2SO4) hydrogen ions each have a +1 charge so since there are 2. In Cu(SO4)2, check the oxidation numbers and add them together, then balance the remainder with the same value but opposite sign. oxidation number O = -2. oxidation number Fe = 0. Same with ZnSO4.. but why is it +2 and not +10?? It is possible to remove a fifth electron to form another the $$\ce{VO_2^{+}}$$ ion with the vanadium in a +5 oxidation state. Thus, Charge on Cu + Charge on Sulphur + (Number of oxygen atoms)* (Charge on Oxygen) = 0 x + (+6) + 4(– 2) = 0 x + 6 - 8 = 0 x - 2= 0 x = +2 It is possible for sulfur to be -2, but is this case, it is actually +6. The oxidation number for Mn in Mn2O7 is + 7. Cu2+ is the oxidising agent. Please explain in detail. Anonymous. the sulfate ion has 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. The positive oxidation state is the total number of electrons removed from the elemental state. Also: Multiplikation der ersten Gleichung mit 5 und dann Addition. Oxygen its -2 each*4=-8 Fe is +2 As we know FeSO4 is neutral, Fe + S + O*4 = 0 i.e. However, many non metals have MULTIPLE oxidation numbers! A negative oxidation number, or “effective charge,” denotes the number of electrons an atom has available to donate as it participates in a chemical reaction to form a new substance. The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements. Chemical reaction. Relevanz.
