Question
Standard electrode potential for Sn4+ / Sn2+ couple is +0.15 V and that for the Cr3+ / Cr couples is - 0.74. These two couples in their standard state are connected to make a cell. The cell potential will be
Options
A.+ 0.89 V
B.+ 0.18 V
C.+ 1.83 V
D.+ 1.199 V
Solution
EoSn4+/Sn2+ = + 0.15 V
EoCr3+/Cr = - 0.74 V
EoCell = Eocathode(RP) - Eoanode(RP)
= 0.15 - ( - 0.74 )
= + 0.89 V .
EoCr3+/Cr = - 0.74 V
EoCell = Eocathode(RP) - Eoanode(RP)
= 0.15 - ( - 0.74 )
= + 0.89 V .
