Question
Why are substances like platinum and palladium often used for carrying out electrolysis of aqueous solutions?
Solution
Answer:
The Plantium and palladium are used for electrolysis of aqueous solution due to the chemically inert in nature and good adsorptive capacity for hydrogen.
Because Gases like hydrogen are absorbed on the surface of platinum and palladium (adsorption) and then passes into the bulk of the adsorbent (platinum and palladium).
