How to Make Oxygen and Hydrogen from Water Using Electrolysis
1 Fill a glass (about 3 in ./7.5cm diameter) about 3/4 full of tap water. 2 Dissolve a teaspoon of table salt in the water . Salt helps conduct electricity better through water. 3 Place a thin piece of cardboard (a paper plate will work) ov... Read More »

Because there are two hydrogen atoms and only one oxygen atom for each water molecule. The atomic volume of hydrogen is 14.4 cm3/mol and the atomic volume of oxygen is 14.0 cm3/mol so you are basically getting 2 units of volume from hydroge...

Answer 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...

Water is made of two hydrogen atoms and one oxygen atom. In its gaseous form, hydrogen atoms bond into pairs. The same is true for oxygen. You might think you could mix a certain number of H2 atoms in their gaseous state with half the numbe...

Not easy to demonstrate, but easy to prove. You light the hydrogen with a match...but that's dangerous and they won't let you do it at a science fair. The chemical reaction is: Cathode (reduction): 2H2O(l) + 2e− → H2(g) + 2OH−(aq); ...
