Two Daniel cells were set up one with 1 M ZnSO_(4) and1 MCuSO_(4) , the other with 2 M ZnSO_(4) and 2 M CuSO_(4) . Their emf's are E_(1) and E_(2) respectively . Then

Answer»

`E_(1) = 2 E_(2)`
`E_(2) = 2 E_(1)`
`E_(2) = 4 E_(1)`
`E_(1) = E_(2)`

Solution :As the factor `[ZN^(2+)]// [CU^(2+)]` remains same , `E_(1) = E_(2)`
