How can hydrogen be produced from water?

Answer 1

By separating the atoms present in the water. Water is H2O, which is 2 atoms of hydrogen and 1 atom of oxygen. At least that's my guess.

Answer 2

if you take a wire from the negative end of a battery, and a positive end of a battery, and put them in water, with a little bit of salt to lower the resistance of the water so electricity can pass through it at low voltages, you will see bubbles coming off the wires, one wire will create oxygen, another will create hydrogen. And by create i mean it will break the bond between the hydrogen and oxygen in the H2O molecule, the one that bubbles the most will be the hydrogen. If you trap the hydrogen in a container, and keep the opening down, you can light a match or a stick lighter at the opening for a cool little explosion.

Answer 3

An interesting question. The usual way is to pass a direct current through water with a small amount of electrolyte such as sulphuric acid added to make it more conductive. Hydrogen bubbles off the cathode (negative electrode) and oxygen from the anode. But work is being done on flat panels which use the energy of sunlight directly to split water, providing hydrogen for fuel. You've got two transparent sheets with water circulating in the thin layer between them. On the insides of the sheets is a thin layer of catalyst. A promising one is chemically a bit like chlorophyll but containing ruthenium instead of magnesium. The catalyst uses the energy of photons to tear the water molecules apart. If it can be made to work efficiently, it promises cheap environmentally friendly fuel.

Answer 4

Hydrogen might nicely be made from water utilising electrical energy, ELECTROLYSIS to be dazzling. Electrolysis is a chemical approach used to break chemical bonded components and compounds utilising an electric powered contemporary. It seperates the oxygen and hydrogen based off their electronegativity. So the beneficial ions (Hydrogen) is going one way (in direction of the cathode) whilst the adverse ions (Oxygen) is going the different (in direction of the anode).

Answer 5

Just get all the oxygen out of it (H20) and Hydrogen is all that is left. You could use a process in which something is introduced that will draw and bind the oxygen, leaving the hydrogen free.

Answer 6

Hydrogen extraction process

Answer 7

Run electricity through water. It will break the molecular bonds, giving you hydrogen (H2) and oxygen (O2.)

Answer 8

adding a metal so that the oxygen bonds to the metal and the hydrogen is left alone

Answer 9

By Electrolysis of the water (with a little salt dissolved in it to assist the electrolysis).
The H+ ions will be liberated at the Cathode.
(Oxygen (O- ions) at the Anode).

Answer 10

There are some tube thingys you use to seperate the hydrogen and oxygen... no clue what they are called though... good luck
