When 48250 C of electricity is passed through an aqueous solution of NiI_(2) (at.mass of Ni = 58.8) , the weight of nickel metal deposited be

Answer»

7.3 gm
14.7 gm
22.0 gm
29.4 gm

Solution :96500 C will deposit 1 gm equivalent i.e. `(58.8)/(2) [("At. Mass")/("valency")]` G of Nickel
`therefore` 48250 C will DEPOSITS `= (48250)/(96500) xx (58.8)/(2) = 14.7` g
