The same quantity of electricity that liberates 4.316 g of silver from `AgNO_(3)` solution was passed through a solution of gold salt. If the atomic weight of gold be 197 and its valency in the above-mentioned salt be 3, calculate the weight of gold deposited at the cathode and the quantity of electricity passed.

A

3.28g, 4021.5 C

B

3.28g, 5023.3 C

C

2.63g, 6213.5 C

D

2.63g, 3864.7 C

Text Solution

Verified by Experts

The correct Answer is:
D
We know that =`(W_(Ag))/(W_(Au))=(E_(Ag))/(E_(Au))`
`therefore Q=(96500xx2.63)/(65.67)=384.7 C`
