Question

On passing one faraday of elecricity throuth the electrolytic cells containing `Ag^+ , Ni^(+3)` and `Cr^(+3)` ion solutions, the deposited Ag `(AT. Wt. = 108) Ni (At. Wt = 59 )` and `Cr (At wt. = 52)` is .
A. `Ag,108 g Ni, 29 . 5 g Cr 17.3 g`
B. `Ag, 108 g Ni, 59.0. 5 g Cr 52.0 g`
C. `Ag, 108 .0 g Ni, 108.0. 5 g Cr 108.0 g`
D. `Ag, 108 g Ni, 117.5. 5 g Cr166.0 g`

Answer 1

Correct Answer - a
Wt.Ag deposited = Eq . Wt of `Ag= 108 g`
Wt. of Ni deposited = Eq . Wt . Of `Ni = 29 . 5 g`
Wt. Of `Cr ` eposited = Eq. wt , of ` Cr = 17 . 3 g`.
