Basically I'm a science nut. I've recently been making my own real-life periodic table of elements. I have everything but the very rare metals (e.g., francium), heavy metals higher than uranium (e.g., plutonium, which is illegal anyway), very expensive metals (e.g., rubidium, cesium) which I'll get later, illegal elements and the gases. Obviously, it's not a complete table but it will end up being as close as a schmuck like me can get. I'm trying to work on getting the gases now. I figure I'll start with hydrogen and oxygen.
First off, how exactly does one reduce the risk of igniting the hydrogen while doing electrolysis. Then, how would I get the hydrogen into a vial in a fairly pure state (>80% pure hydrogen). I ask this because there's no way of knowing if your getting a vial full of hydrogen or completely full of lame air. Thanks!
