Creating A Hydrogen Gas Generator
Warning: Hydrogen gas is highly flammable and can explode. When generating hydrogen keep away from electricity or some source of ignition in the case of a leak. If generating over night place outdoors to avoid explosion. This website is not responsible for any malfunctions with your own experiment(s).
We’ve all heard of Helium and how a balloon will fly if it’s filled with the element. But did you know that hydrogen, the H in H2O, is even lighter than helium, but it’s not used because it’s highly flammable.
For this experiment you’ll need:
3) A battery
4) Some form of a container that is flexible (like a garbage bag).
1) Fill some form of a container (that you’re willing to sacrifice) up to the brim with water and then fill it up to about 3/4 of a centimeter with salt.
2) Then gently drop the battery over a sink, allowing the water to overflow.
3) Now Hydrogen should be forming, which is the cloud, seen in the image above, surrounding the spring. When collecting this hydrogen I recommend you do not use a balloon since the hydrogen with permeate through, I learned that the hard way. Instead use a trash bag. What I did below was attach a long tube, but the tube had a leak that was undetectable.
When you want to generate certain amounts of hydrogen follow this rule: The higher the voltage the more hydrogen
I used a 6v battery that was “dead” when used with a flashlight. This would’ve given me about 2x the amount a normal AA-Battery would. The video below shows a AA-Battery in action. When you see the water turn brown and then green, and then black, that’s normal. That’s the rust accumulating from the battery. WHEN HYDROGEN IS NO LONGER GENERATING DO NOT POUR THE LIQUID DOWN A DRAIN, THE MILD AMOUNT OF BATTERY ACID COULD, POTENTIALLY, DAMAGE YOUR PIPES.
Well that’s how you generate hydrogen gas from water.
