Ask â¦ +2 to 0. Relevance. zn+cuso4=znso4+cu oxidation? In almost all cases, oxygen atoms have oxidation numbers of -2. Zn + CuSO4 -----> Cu + Zn SO4 this is, no doubt, a redox equation. Oxidation no. Calculation of oxidation state of âCuâ in CuSO4 molecule: Let the oxidation state of âCuâ is âxâ. Please explain in detail. of Cu changes from +2 to 0 thus it undergoes reduction. Same with ZnSO4.. but why is it +2 and not +10?? Update: so let's say I don't have the equation. +2 + 2S +(8×-2) = +2 +2S -16 = 2S -14, so 2S = +14. Answer to: Which of the following chemical reactions is an oxidation-reduction reaction? What is the oxidation number of S in CuSO4? +2 The proper name for CuSO_4 is copper(II) sulphate - the Roman numerals denote the oxidation state for any atom which has variable oxidation states, such as transition metals. Answer Save. Cu2+ is the oxidising agent. (a) Hg(l)->Hg(g) (b) 3O2(g)->2O3(g) (c) CuSo4*5H2O(s)->CuSO4(s)+5H2O(g) (d) H2(g)+F2(g)->2HF(g) At constant pressure, in which of the reactions is work done by the system on the surroundings? Anonymous. What is the oxidation number of CuSO4? Answer Save. How would u figure it out??? SO4 (sulphate) has a -2 charge. The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements. 5 years ago. of Zn changes from 0 to +2, thus it undergoes oxidation. From there, you can work out the value for S. S + 4O = -2 S + 4(-2) = -2 S = -2 + 8 S = +6-sulfur is+6, oxygen is -2 x 4, for a net ionic charge of -2. SO4 is 2-, oxygen is -2 each*4 = -8 Fe is 2+ You can set it up like this S + 4(-2) = -2 S + -8 = -2 S = -2 + 8 S = 6 Charge of sulfur in FeSO4 is +6-Sulphate always has a charge of -2, so S + 4O = -2. Chemistry. 1 decade ago. Announcements Struggling to make your uni choices? 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. Assign an oxidation number of -2 to oxygen (with exceptions). The coordination number is 4, because it is coordinated to 4 NH3 molecules (SO4 is just a counter ion, not coordinated). The oxidation number of O in compounds is usually -2, but it is -1 in peroxides. Does hydrogen undergoes reduction or oxidation on the basis of oxidation number in 2NH3 +H2SO4 which gives (NH4)SO4 .

Find your group chat here >> start new discussion reply. i just don't get oxidation number for example, in CuSO4 O: (-2)x4= -8 S= -2 so shouldn't Cu be +10?? Remember the mnemonic "oil rig": oxidation is loss, reduction is gain. You do not need two waters of hydration to form the Cu(NH3)4(H2O)2 complex, in the crystalline form it can exist as a monohydrate. +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. Then, it would only need 2 electrons. the sulfate ion has a -2 charge.
