🧠 The Anodic Competition
At the anode (the "positive" electrode), anions compete to lose their electrons (oxidation). In dilute sulphuric acid, we have  and water (). Water usually wins the fight because it's easier to oxidize than the sulphate ion.

🗺️ The Electrochemical Play
1. The Rivals: Oxygen is in the  state in water, and Sulphur is in the  state in sulphate.
2. The Reaction: 
   
3. The Result: Oxygen gas is evolved at the anode.
4. Why not Sulphate?: The oxidation of  requires much h
