NCERT Solutions; Board Paper Solutions; Ask & Answer ; School Talk; Login; GET APP; Login Create Account. CuSO4 is a neutral molecule ... so the sum of the oxidation numbers is zero. Thanks in advance. ; When oxygen is part of a peroxide, its oxidation number is -1. . +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. In . It has gained electrons, so it is reduced. What is the oxidation number of S in CuSO4? Pizza. The oxidation number of sulphur in( NN4)2so4 . We could start from a knowledge that the sulphate ion has a 2- charge, so the copper ion must have a 2+ charge and hence a +2 oxidation number. Since sulfate (#"SO"_4^(2-)#) is already … Chemistry . Announcements Struggling to make your uni choices? For MgH2 the oxidation number of Mg is +2 [because group 2 metals are always +2] so the oxidation number of H is -1. I know the answer is +6, I know that my equation to figure this out should look similar to below: 1(2)+x+4(-2)=0. Favourite answer. Relevance.
