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) + 2Cu2(aq) + 5OH (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)

Best answer

(a) Oxidised substance → C6H6O

Reduced substance → AgBrO

xidising agent → AgBr 

Reducing agent → C6H6O

(b)Oxidised substance → HCHO 

Reduced [Ag(NH3)2]+ substance → 

Oxidising agent → [Ag(NH3)2]+

Reducing agent → HCHO 

(c) Oxidised substance → HCHO 

Reduced substance → Cu2+

Oxidising agent → Cu2+ 

Reducing agent → HCHO 

(d) Oxidised substance → N2H

Reduced substance → H2O

Oxidising agent → H2O

Reducing agent → N2H

(e) Oxidised substance → Pb 

Reduced substance → PbO

Oxidising agent → PbO

Reducing agent → Pb
