A certain quantity of current on passing through electrolytic baths containing AgNO3, FeSO4 and CrCl3 in series, and 'x' of chromium metal is deposited. The ratio of of Ag and Fe is deposited in the ratio of
(1) x, 2x
(2) 3x, 2x
(3) 3x, 3x/2
(4) x, x
Correct option (3) 3x, 3x/2
Explanation:
Mass of element electrodeposited is proportional to equivalent mass of element.
Equivalent masses of Ag : Fe : Cr in terms of molar mass M
Ratio of ***** of electro deposited
3x : 1.5x = x
