Electrolysis of Water H2O Lab Version
Channel: MortimerCCScience
Date: 2013-03-15

This is a demo of water electrolysis using a Hoffman Voltameter.

We are testing for the gases using a lit splint, hydrogen will 'pop' and oxygen will relight the glowing splint.

The 'water' is actually 1M sulphuric acid but it acts as a catalyst and speeds the practical up (and is still pretty slow!)

Equipment needed:
* Hoffman Voltameter (or daniel cell, either works)
* 1M sulphuric acid
* Power Pack set to 12V with wires and crocodile clips
* matches and a wooden splint
