how can oxygen be removed from water?

Question

If h2o is 2 hydrogens and 1 oxygen if one was to remove the oxygen atom one would be left with pure hydrogen.

Answer 1

With the extra information in the question, yes, using a process that breaks the O-H bonds in water and allowing the hydrogen to combine with other hydrogen atoms will remove oxygen atoms from the water molecule. Electrolysis, mentioned before, is one of those ways.

However, the main part of your question is interpretable in another way. Oxygen gas is dissolved in water. This is not trivial as that's how everyone creature on earth with gills gets their oxygen. Since the solubility of gases decreases with increasing temperature of the solution, simply heating up the water and letting it cool in a non-oxygenated atmosphere (say pure nitrogen) should do the trick.

Answer 2

Correct. Done every day by industry and nature.

It takes exactly as much energy to separate H2O into its component atoms as is generated by burning the same amount of hydrogen and oxygen.

The Space Shuttle main engines burn pure hydrogen and oxygen in liquid forms.

Answer 3

There ia a cheap none electrical to remove ox from a fluid. when making wine yeast is added to must to create colony of yeast they require oxygen ro survive a t first during the groth of the coliny the are comes from the top of the vessel later the lid is attached and a air prevented is used (Balloon, air lock, bubblier). now the ox for the colony is commiong from the water ie h2o

Answer 4

All you have to do is run electricity through the water, but the hydrogen that results will contain less energy and the energy it took to make the hydrogen

Answer 5

easy. read the from the link below to get the idea. all you have to do is capture it. do a search for how to make hydrogen
you then will come up with several methods. Going to make some and run things on it around my place. maybe even a heater for winter?

Answer 6

You can do it with a DC current and some copper wires.

But, once you burn the hydrogen and use it to generate electricity, you'll have a net loss of energy.

Answer 7

It's called electrolysis, and nuclear submarines use it to get oxygen from seawater.



In chemistry and manufacturing, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them.

Answer 8

It can be removed with electricity and is to generate hydrogen.

Answer 9

I think this is hilarious. To get oxygen you (in order of appreance)

use electrolysis
use electrolysis
use electrolysis
use electrolysis
use electrolysis
make ice

Ha.

Answer 10

using electrolysis you can separate H2 and O2 from water, but it is timely and energy inefficient
