Four suvvessive members of the first series of the transition metals are listed below. For which one of them the standard potential (E_(M^(2+)//M)^(@)) value has a positive sign

Answer»

`CO(Z=27)`
`Ni(Z=28)`
`CU(Z=29)`
`FE(Z=26)`

Solution :`E_(Cu^(+2)//Cu)^(o)=0.34`volt, other has `-veE_(R.P.)^(o)`
