hi all, I was doing electrolysis to produce hydrogen. I start getting a gas that is so mysterious to my science knowledge. When i put fire into it, it eat up the flame and put out the lighter. AT first I thought that must be carbon-dioxide (fire extinguisher reagent). Then i put some soap into the surface of the solution and collect that gas in bubbles. When i put fire in it, it explode. I am convinced that it is hydrogen. This contradict to science that hydrogen is flamable. I read a government physics document said that the reaction of hydrogen and oxygen is a colorless flame. Then there must be a present of something that make hydrogen combust into a real visible flame in the air... It seems like hydrogen will be friendly to friendly element(thus produce so low temperature,colorless flame) and aggressive with aggressive element (metal) (produce a high temperature, visible flame) .
