cell Rxn: Ox(1) + Red(2) + other -> Red(1) + Ox(2) + other Eo (V) n Fe/Fe2+//Sn2+/Sn Sn/Sn2+//Ag1+/Ag Pt/I2,I1-//Au3+/Au

Explanation / Answer

Cell Rxn Eo (V) n

Fe/Fe+2//Sn+2/Sn Fe + Sn+2 = Fe+2 + Sn Eo= ESn+2/Sn - EFe+2/Fe= 0.30 2

Sn /Sn+2//Ag+1/Ag Sn + 2Ag+1 = Sn+2 + 2Ag  Eo= 0.94 2

Pt/I2/I-//Au+3/Au 6 I- + 2Au+3= 3I2 + 2Au Eo= 0.84 6

Standard reduction potential values is used.
