The Total solution for NCERT class 6-12
Identify the substance oxidised, reduced, oxidising agent and reducingagent for each of the following reactions :
1. 2AgBr(s) + C6H6O2(aq)→2Ag(s) + 2HBr(aq) + C6H4O2(aq)
2. HCHO(l) + 2[Ag(NH3)2]+(aq)+ 3OH–(aq) → 2Ag(s) + HCOO– (aq) + 4NH3(aq)+ 2H2O(l)
3. HCHO(l) + 2Cu2+(aq)+ 5OH–(aq)→ Cu2(O(s) + HCOO-(aq) + 3H2O(l)
4. N2H4(l)+ 2H2O2(l) →N2(g) + 4H2O(l)
5. Pb(s) + PbO2(s)+ 2H2SO4(aq)→ 2PbSO4(s) + 2H2O(l)
AgBr : reduced ; acts as oxidising agentC6H6O2 : oxidised ; acts asreducing agent.
