A solution is one molar in each of NaCl , `CdCl_(2) , ZnCl_(2) and PbCl_(2)` . To this , tin metal is added . Which of the following is true ? Given : `{:(E_(Pb^(2+) |P)^(@) = -0.126 V "," E_(Sn^(2+)|Sn) = -0.136 V) , (E_(Cd^(2+)|Cd)^(@) = -0.40 V "," E_(Zn^(2+)|Zn)^(@)= -0.763 V), (E_(Na^(+) |Na)^(@) = -2.71 V):}`A. Sn can reduce `Na^(+)` to NaB. Sn can reduce `Zn^(2+)` to ZnC. Sn can reduce `Cd^(2+) ` to CdD. Sn can reduce `Pb^(2+)` to Pb . |
