Note : * The chemical which gains electrons is reduced (reduces its valency) and is … Please explain in detail. 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 Fe goes from oxidation number 0 to +2. 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. In Cu(SO4)2, check the oxidation numbers and add them together, then balance the remainder with the same value but opposite sign. so CuSO4, the Cu has to have +2 charge to have equal … Same with ZnSO4.. but why is it +2 and not +10?? so the oxidation number of Cu is +2. In CuSO4, sulphur will have the oxidation number +6. Chemistry So, reduction decreases the oxidation number (valency). +6: Oxygen in oxyanions is assumed to have an oxidation state of -2; there are four such oxygen atoms, for a total of -8, and the SO4 anion has a charge of -2. Since it is a neutral molecule summation of charges on the molecule is zero. Hope this makes sense. Yes.
