Standard electrode potential for Sn^(4+)//Sn^(2+) couple is +0.15V and that for the Cr^(3+)//Cr couple is -0.74V. These two couples in their standard state are connected to make a cell. The cell potential will be

Answer»

`+1.83V`
`+1.19V`
`+0.89V`
`+0.18V`

SOLUTION :`E_(CELL)^(@)=E_("cathode (RP)")^(@)-E_("anode (RP)")^(@)`
`=0.15-(-0.74)=+0.89V`
