Bredig's arc method cannot be used to prepare colloidal solution of which of the following

A

`Pt`

B

`Fe`

C

`Ag`

D

`Au`

Text Solution

Verified by Experts

The correct Answer is:
B
Bredig's arc method is suitable for the preparation of colloidal solution of metal like gold silver, platimum etc. An arc is struck between the metal electrodes under the surface of water containing some stabilizing agent such as a trace of `KOH`. However , `Fe` does not react with alkalies that is why it is not obtained by Bredig's arc method.
