@PyroCrosser1 : Wel een beetje oppassen. Dus: handschoentjes aan, bril op en wat je overhoudt netjes bij het chemisch afval. Net als een gewone batterij.
Hydrogen doesn't "bang". It starts burning like any other flammable gas, only almost invisible.
What you got is a mixture of hydrogen and oxygen, a very poor one I might say, because oxygen is leaking into the electrolyte and the water in the second beaker.
If you want hydrogen, separate it in the cell, and if you want a stoichiometric detonating mixture, boost up the amperes (use a car battery charger). That will produce enough of both gasses so that oxygen leaking won't have a large effect.
@endimion17, sure, there are ways to tweek this experiment. But in this case, we wanted to keep it simple. And under the right conditions, hydrogen can give a bit of a bang, see the experiment we did earlier (can't put a link here, so search for Hete vloeistof, explosief gas).
@CGBoem Bangs are produced by explosive mixtures, not raw fuels. It will ignite quickly because it's very light and mobile,but bangs no.
I went to see that video. That was not hydrogen. It was a mixture of wet hydrogen and air. Pure samples of hydrogen are collected after it displaces air from the reaction apparatus, which takes a minute or two for the size of the flask you used.That way you can even light it at the vessel's vent hole and nothing will detonate.It will burn with a diffused flame.
@endimion17, I'm sure you're right, but the series in which we do these experiments is called 'Cogito ergo Boem' in which the Dutch word Boem stands for 'Bang'. So talking about a hydrogen bang is a pun rather than a scientific statement... Also, it was the last in that years series so we were going out with a bang(-ish sort of plopping sound).

Mooie opstelling met zeepsop!
Ik hoop niet dat het keukenzout is, want dan krijg je geen zuurstof maar chloor.
Op amateurchemie.nl zijn ook veel proeven, misschien leuk om daar ook te posten?
