Calculate the current ( in Ma) required ...

Calculate the current ( in `Ma)` required to deposit `0.195 g` of platinum metal in `5.0` hours from a solution of `PtCl_(6)^(2-) : (` Atomic weight `: pt = 195 )`

A

310

B

31

C

21.44

D

5.26

Text Solution

Verified by Experts

The correct Answer is:
3
`(W)/(E)=(Ixxt)/(96500),(0.195)/(195)xx4=(5xx60xx60xxI)/(96500)`
`I=21.44`
