Used to have to do this by cooling (liquidifacation),
by now they've got semi-permeable membranes that can do the job.
When you separate H2O, you will get hydrogen gas (H2) and oxygen gas (O2) as separate entities. This process usually involves electrolysis, where an electric current is passed through water to break it down into its constituent elements.
A container of hydrogen gas and oxygen gas contains separate molecules of H2 and O2, while a container of water vapor contains H2O molecules. The hydrogen gas and oxygen gas in the first container can react to form water vapor under certain conditions.
Water can be electrolyzed by passing an electric current through it, which causes the water molecules to break apart into hydrogen and oxygen gases. This process occurs at the electrodes, where hydrogen gas is produced at the cathode and oxygen gas is produced at the anode.
In the decomposition of water, water molecules are broken down into oxygen gas and hydrogen gas through a process called electrolysis. This requires passing an electric current through water to separate the hydrogen and oxygen atoms.
Hydrogen can be turned into water and oxygen through a chemical reaction called electrolysis. By passing an electric current through water (H2O), the hydrogen and oxygen atoms will separate, producing hydrogen gas (H2) at one electrode and oxygen gas (O2) at the other electrode.
In electrolysis, oxygen and hydrogen gas are produced at different electrodes (oxygen at the anode and hydrogen at the cathode). Since these electrodes do not have to be in close proximity, the hydrogen and oxygen will bubble upwards into separate collection vessels. If you needed to separate hydrogen and oxygen once mixed, the easiest way I can think of would be to cool the mixture to ~60K. At this point the oxygen would condense and leave hydrogen gas.
Use a distillation column. It cools down the gases to below the boiling point of oxygen at high preassure. Oxygen condenses and forms a liquid that can be tapped from the column while hydrogen remains a gas. Why not separate the electrodes used in the electrolyzation process and trap hydrogen at one and the oxygen at the other? It is a lot easier, and probably a lot less dangerous (as a hydrogen and oxygen gas mixture is explosive).

oxygen gas is heavier than hydrogen gas
Water can be electrolyzed by passing an electric current through it, which causes the water molecules to break apart into hydrogen and oxygen gases. This process occurs at the electrodes, where hydrogen gas is produced at the cathode and oxygen gas is produced at the anode.
Hydrogen gas is H2. Oxygen gas is O2.

Hydrogen can be separated from water through a process called electrolysis. In this process, an electric current is passed through water, which causes the water molecules to split into hydrogen and oxygen gas. The hydrogen gas is then collected at one electrode, while oxygen gas is collected at the other electrode.
When water splits, hydrogen gas and oxygen gas are formed.
