Justify that the reaction: 2Cu2O(s) + Cu2S(s) ---------> 6Cu(s) + SO – InterviewSolution

InterviewSolution

1.	Justify that the reaction: 2Cu2O(s) + Cu2S(s) ---------> 6Cu(s) + SO2(g) is a redox reaction. Identify the species oxidised/ reduced, oxidant and /reductant.
Answer» Cu₂O helps sulphur in Cu₂S to increase its oxidation number, therefore, Cu(I) is an oxidant; and sulphur of Cu₂S helps copper both in Cu₂S itself and Cu₂Oto decrease its oxidation number; therefore, sulphur of Cu₂S is reductant.
