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,Ni,Cr,),(108 g,29.5 g,17.3 g,):}`
B. `{:(Ag,Ni,Cr,),(108 g,59 g,52 g,):}`
C. `{:(Ag,Ni,Cr,),(108 g,108 g,17.3 g,):}`
D. `{:(Ag,Ni,Cr,),(108 g,29.5 g,166 g,):}`

Answer 1

Correct Answer - A
Equivalent mass of `Ag = (108)/(1) = 108`
Equivalent mass of `Ni = (59)/(2) = 29.5`
Equivalent mass of `Cr = (52)/(3) = 17.3`
`:.` Amount of these metals deposited by 1 faraday charge will be: 108 g Ag, 29.5 g Ni and 17.3 g Cr respectively
