On passing current through KCl solution,...

On passing current through KCl solution, 19.5 g of potassium is deposited. If the same quantity of electricity is passed through a solution of aluminium chloride, the amount of aluminium deposited is

A

4.5 g

B

9.0 g

C

13.5 g

D

27 g

Text Solution

Verified by Experts

The correct Answer is:
A
`("Weight" of K)/("Weight" of AI)=(Eq."Weight" of K)/(Eq."Weight" of AI)`
`19.5/w_(AI)=39/(27/3)`
`w_(AI)=27/3xx19.5/39=4.5` g
