Standard electrode potential for Sn^(4+)//Sn^(2+) couple is+ 0.15 V and that for the Cr^(3+) //Crcoule is -0. 74 V. These two coules in their standard state are connected to made a cell. The cell potential wil be .

Answer»

SOLUTION :GIVEN : `E_(SN^(4+)//Sn^(2+))^(@)=0.15V`
`E_(Cr^(3+)//Cr)^(@)=-0.74V`
`E_("cell")=E_(Sn^(4+)//Sn^(2+))^(@)-E_(Cr^(3+)Cr)^(@)`
`=0.15-(-0.74)`
`=0.89V.`
