Is Electrolysis the only way of splitting Water into Hydrogen and Oxygen?

I read about the splitting of chemically bonded elements by means of passing an electrical current through it (Electrolysis), and of how water is subsequently split into hydrogen and oxygen, respectively, through this by the Hoffman apparatus test. Is it possible, however, to split water from it's least stable form (Steam) mechanically, ie: turbulently accelerating it through an enclosed tube by means of a strong vacuum? ...Or any other way mechanically?Is Electrolysis the only way of splitting Water into Hydrogen and Oxygen?
Yes there is. One famous incident of the decomposition of water occurred accidentally in 1979 in a place called Three Mile Island. Three Mile Island is a nuclear power station and was the site of a near-meltdown. In the damaged reactor vessel the temperature and pressure were very high and the cooling water in the vessel decomposed to form hydrogen gas and oxygen gas. One of the fears was that the two elements might combine explosively and potentially rupture the vessel. Luckily it didn't happen.





So the bottom line is that under conditions of high temperature and pressure water can decompse thermally into H2 and O2.Is Electrolysis the only way of splitting Water into Hydrogen and Oxygen?
sorry hun I dont think there is. the electrosis is the only possible way and if there was another way it would take a very long time as even the electrosis experiment takes long enough. but anyway you can try to experiment with new ways of splitting water into hydrogen and oxygen,who knows you might make history =]


have fun trying honey

I don't know what you want to consider mechanical. I could envision an enzyme that might break it apart. Collision with a high energy nuclear particle might do the job.





Of course, chemical reactions can liberate the hydrogen and oxygen from water.
Water can be broken into H2 and O2 by applying sufficient heat to decompose the bonds in the molecule, a very inefficient way of doing this.


An appropriate catalyst that works with sunlight might also be effective in decomposiing water into H2 and O2.


Water is also decomposed in photosynthesis to produce O2, but the H2 is retained in the resulting glucose molecules.
