The desired amount of charge for obtaining one mole of \(Al\) from \(A{l^{3 + }}\)
1 \(3 \times 96500\,\,C\)
2 \(96500\,\,C\)
3 \(\frac{{96500}}{3}C\)
4 \(\frac{{96500}}{2}C\)
Explanation:
(a)\(Al \to A{l^{3 + }} + 3{e^ - }\). The charged obtained is \(3 \times 96500\,C\).

On passing one faraday of electricity through the electrolytic cells containing \(A{g^ + },\,N{i^{ + 2}}\) and \(C{r^{ + 3}}\)ions solution, the deposited \(Ag\,(At.\,wt. = 108),\,Ni\,(At.\,wt. = 59)\) and \(Cr\,(At.\,wt. = 52)\) is\(Ag\) , \(Ni\) , \(Cr\)
1 \(108\,gm\), \(29.5\,gm\), \(17.3\,gm\)
2 \(108 \,gm\), \(59.0\,gm\), \( 52.0\,gm\)
3 \(108.0\,gm\), \(108.0\,gm\), \( 108.0 \,gm\)
4 \(108 \,gm\), \(117.5\,gm\), \( 166.0\,gm\)
Explanation:
(a) Wt. of \(Ag\) deposited $=$ Eq. wt. of \(Ag = 108\,gm\). Wt. of \(Ni\) deposited $=$ Eq. wt. of \(Ni = 29.5\,gm\) Wt. of \(Cr\) deposited $=$ Eq. wt. of \(Cr = 17.3\,gm\).
