On electrolysis of dil. sulphuric acid using Platinum (Pt) electrode the product obtained at anode will be: Oxygen gas gas gas Hydrogen gas
Multiple Choice Options
- A Oxygen gas
- B H 2 S gas
- C SO 2 gas
- D Hydrogen gas
Step-by-Step Verified Solution
During the electrolysis of dil. sulphuric acid using Pt electrodes following reaction will take place.
At cathode :
4 H ( a q ) + + 4 e _ _ 2 H 2 ( g )
At anode :
2 H 2 O ( I ) _ O 2 ( g ) + 4 H ( a q ) + + 4 e _
At the anode oxygen gas will be released.
