Calculate the current (in mA) required to deposite 0.195g of platinum metal in 5.0 hours from a solution of `[PtCl_6^(2-)`:(Atomic mass:Pt=195)

A

310

B

31

C

21.44

D

5.36

Text Solution

Verified by Experts

The correct Answer is:
C
`(W)/(E) = (I xx t)/(96500) , (0.195)/(195) xx 4 = (5 xx 60 xx 60 xx I)/(96500)`
`I = 21.44` m A
