I 2S O S O 2I → In the above reaction: (CPMT 2009)

The given reaction can be written as: - - 5 4S(+2)+2e 4S( ) 2 2I(0)+2e 2I(-1) → → Oxidation state of sulfur has increased, but that of iodine is decreased. Therefore, Sulfur is oxidized and Iodine is reduced. REDOX REACTIONS 30 11. For the redox reaction, 2 3 4 Zn NO Zn NH → In basic medium, coefficients of Zn, 3 NO and OH– in the balanced equation respectively, are (Manipal 2009) (a) 4, 1, 7 (b) 7, 4, 1 (c) 4, 1, 10 (d) 1, 4, 10 The given reaction is- - +2 + 3 4 Zn+NO Zn +NH → We write the reaction in two halves- Oxida
