Describe the electrolysis of water.

Describe the electrolysis of water.

---

Pure water does not conduct electricity. For this reason 2 or 3 mL of dilute sulphuric acid or
dilute sodium sulphate solution is added to the water in the electrolysis cell.

Connect the cell to the DC supply and watch for bubbles of gas at both electrodes. If none
appear, add a little more acid or sodium sulphate solution. After 5 to 10 minutes there
should be enough hydrogen and oxygen gas for testing. Predict at which electrode each gas
will appear.
