Question

Justify that the reaction: 2Cu2O(s) + Cu2S(s) → 6Cu(s) + SO2(g) is a redox reaction. Identify the species oxidised/reduced, which acts as an oxidant and which acts as a reductant.

Which of the following species, do not show disproportionation reaction and why ? ClO–, ClO2–, ClO3– and ClO4– Also write reaction for each of the species that disproportionates.
