How do you separate hydrogen and oxygen gas after you make it from electrolysis?

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).

Which chemical is used in submarines to form oxygen?
Chemicals aren't used to make O2 on board modern submarines; they use electrolysis to separate the Hydrogen and Oxygen in DI water, then store the O2 in tanks outside the pressure hull. The hydrogen is bled overboard as tiny bubbles (in the wine.... make me feel happy...make me feel fine).
How do you make hydrogen from salt water?
You need to electrolyse it. Hydrogen will be produced at the cathode.
What apparatus is used to make oxygen?
One way is to dip wires from a battery into water. Oxygen bubbles appear at the positive wire (and hydrogen at the negative). This method is called electrolysis.
Justify why electrolysis of water is a chemical irreversible change?
A chemical change is always irreversible; that's part of the definition of "chemical change". This is because a new substances with new properties are formed. In this example, hydrogen and oxygen gas.
What 3 element make up fatty acids?
Carbon, Hydrogen, and oxygen
What is electrolysis used to make?
Electrolysis is used to separate sodium metal from table salt. It is easier to harvest hydrogen from fossil fuels, than it is to separate hydrogen from oxygen using electroysis of water.

How do you make oxygen from chemicals?
Since oxygen is an element, it can not be made from chemicals. Instead, it can be separated from compounds. For example, water is made from molecules containing hydrogen and oxygen. When the bond between these two elements is broken by electrolysis, both the oxygen and the hydrogen can be collected.
What are some experiment that involve electricity?
Try using electrolysis to separate the oxygen from the hydrogen in water. How about making electricity with a lemon and two nails, or you could make an electro magnet by winding a coil around a nail and connecting it to a battery.

What two elements is water made up of?
Oxygen and hydrogen are the two ellements that make up water.
Cost to make a electrolysis?
There are two common definitions for electrolysis, both using electric current. Scientists use electric current to cause chemical changes, such as converting liquid water into hydrogen and oxygen gases. It costs very little to do this experiment (see http://www.wikihow.com/Make-Oxygen-and-Hydrogen-from-Water-Using-Electrolysis). Electrolysis also refers to the cosmetic use of electric current to permanently remove body hair. The current both loosens the hair for easy removal and kills the root of the hair to prevent regrowth.

How do you make more hydrogen from water?
You'd have to part it from the oxygen it's connected to. This involves electrolysis, which requires lots of energy, and then ensuring spearation, which requires a lot of thinking.
Can cars run on water?
Yes,if you use electrolysis to diffuse oxygen from hydrogen.You will have to suck the hydrogen from the electrode the compress it to make it a liquid now you can use it as fuel.(This is my invention).
Why should hydrogen be the fuel of the future?
To save the environment and make sure that the world do not go under. ---- Hydrogen is found in water that we have a lot of, using electrolysis we could draw out hydrogen and oxygen in separate gases. In modern cars, we could stake rows of fuel cells that use the hydrogen we just made; this cell produces electrical currency that powers the car. In addition, out of the exhaust it will drip water.
