Question

When do we get to see halogen gas forming at the anode?

• A. If the electrolyte has halogen in it
• B. If the electrolyte has polyatomic ion in it
• C. If the electrolyte has oxides
• D. If the electrolyte is charged up by HCl acid

Answer 1

The correct option is A

If the electrolyte has halogen in it

If the electrolyte has a simple ion like the halogens then the gas formed is halogen at anode. In case the electrolyte has either carbonates, nitrates or polyatomic ions then we are bound to see oxygen gas at the anode.
