water electrolosys rate

Funny I did this experiment for my Seventh grade science fair lol. The only part that I remember is setting the hydrogen on fire afterwards and it made a very satisfying pop. Unfortunately Hydrogen fire is clear, so you couldn't see it. Also, you will probably want to use a larger volume than one mL so you get more accurate results (the larger the volume, the less effect a small problem in your experiment has). Hope this helps. Cheers!
