Let me show the procedure how to balance a given equation in both aci dic and basic medium Acidic medium reduction oxidatiar Step: 1 Oxi dati on half reaction NO > NO Reduction half reacti on: Ag>Ag Step: 2 Balancing oxidati on half reaction: NO ^ NO^ Balancing O Balancing H Balancing charge NO + 2H20NOj 4H+3e Step:3 balancing reduction half reaction: Ag> Ag Ag +leAg Balancing charge Step 4: Equalizing theno of electron lost in oxi dation half reaction andno of electrons gainedin reduction half reaction (Ag+le>Ag )x3 Step 5: Adding both thehalf reactions and cancel the common ions to get the balanced equation 3Ag+ +3e--> 3Ag

Basic medium reduction oxidatiar Step: 1 Oxi dati on half reaction NO NO. Reduction half reaction: Ag> Ag Step: 2 Balancing oxidation half reaction: NO ^ NO3 Balancing O Balancing H NO + 2H20+ 40H > NO 4H2C NO + 40H > NO; + 2H2O Balancing charge:NO + 4OH > NO^ + 2H20+3e Step: 3 balancing reduction half reaction: Ag> Ag Ag +le- Ag Balancing charge Step 4: Equalizing theno of electronlostin oxi dati on half reaction andno of electrons gainedin reduction half reaction. (Ag+leAg)x3 Step 5: Adding both thehalf reactions and cancel the common ions to get the balanced equation NO +40H > NOj + 2H20+3e NO +4OH 3Ag NO% + 2H2O +3Ag
