10. An oxide of metal (atomic wt = 112) contains
12.5% 0, by weight. The oxide was converted into
chloride by treatment with HCl and electrolysed.
Calculate the amount of metal that would be
deposited at cathode if a current of 0.965 A was
passed for a period of 5 hours. What is the
valency of metal?
(1) 10 g, valency = 2 (2) 20 g, valency = 3
(3) 30 g, valency = 1 (4) 40 g, valency = 2
