Atomic weight of Al is 27.5 Faraday of electricity is passed in the solution of `Al^(3)+` ions. Which of the following amounts of Al will b e deposited at the cathode?

A

27g

B

36g

C

45.0g

D

9.0g

Text Solution

Verified by Experts

The correct Answer is:
C
Faraday liberates one g equivalent of a substance
`1F=9g ` of Al
`therefore 5F=9xx5=45` of Al
