What is the difference between a bottle of water and a bottle of hydrogen and oxygen?
Answer Hi Daniel, Not much other then the fact that Hydrogen and Oxygen are both gases and that the bottle for the hydrogen would be twice as big (or more) then the bottle of oxygen. Water is “rusty” hydrogen. Or oxidized hydrogen, which if compaired to FeO (Iron Oxide) or AlO (Aluminum Oxide) are oxidized or “rusty” metals. The combination of Oxygen and Hydrogen to make water occurs high in the atmosphere during electrical storms. You need to “burn” hydrogen in the presence of Oxygen to make water. In the same way you can split water into hydrogen gas and oxygen gas by putting electrodes (and a current) into a beaker of water and from one side you will get oxygen bubbling up and from the other hydrogen. This is called Hydrolisys.
