Question

Identify the substance oxidised, reduced, oxidising agent and reducing agent for each of the following reactions: (a) 2AgBr (s) + C6H6O2(aq) → 2Ag(s) + 2HBr (aq) + C6H4O2(aq) (b) HCHO(l) + 2[Ag (NH3)2] + (aq) + 3OH - (aq) → 2Ag(s) + HCOO - (aq) + 4NH3(aq) + 2H2O(l) (c) HCHO (l) + 2Cu 2+(aq) + 5 OH - (aq) → Cu2O(s) + HCOO - (aq) + 3H2O(l) (d) N2H4(l) + 2H2O2(l) → N2(g) + 4H2O(l) (e) Pb(s) + PbO2(s) + 2H2SO4(aq) → 2PbSO4(s) + 2H2O(l) also justify that it is a redox reaction
