How many minutes will it take to plate out 5.2g of cr from a `Cr_2(SO_4)_3` solution using a current of 9.65 A ? (Atomic mass:Cr=52.0)

A

200

B

50

C

100

D

103

Text Solution

Verified by Experts

The correct Answer is:
B
`5.2 = (52)/(3) xx (9.65)/(96.500) xx t` (sec) , t (sec) = 3000
t( min) = 50
