A direct current deposits deposits 54 g ...

A direct current deposits deposits 54 g of silver (Atomic mass = 108) during electrolysis. How much aluminimum (Atomic mass =27) would be deposited from aluminium chloride solution by the same amount of electricity ?

A

4.5 g

B

5.4 g

C

54 g

D

2.7 g

Text Solution

Verified by Experts

The correct Answer is:
A
Equivalent mass of silver = 108
Equivalent mass of aluminium in `(AlCl_(3))=27/3 =9`
`W_(Ag)/W_(Al)=E_(Ag)/E_(Al)`
`54/W_(Al)=108/9`
`W_(Al)=4.5 g`
