Water undergoes electrolysis to form oxygen gas& hydrogen gas?

Answer 1

Yes it does. The balanced equation is:

2 H2O (l) (electricity) ---> 2 H2 (g) + O2 (g)

You will produce twice as much H2 gas as you do O2 gas.

Answer 2

Of course, Electrolysis of water is an electrolytic process which decomposes water into oxygen and hydrogen gas with the aid of an electric current, where a power source is used. The electrolysis cell consists of two electrodes (usually an inert metal such as platinum) submerged in an electrolyte and connected to opposite poles of a source of direct current.

The electric current disassociates water molecule into hydroxide and hydrogen ions.
In the electrolytic cell, at the cathode, hydrogen ions accept electrons in a reduction reaction that forms hydrogen gas:
Cathode(reduction) : 2H2O(l) + 2e- ----> 2H2(g) + 2OH-(aq)

At the anode, hydroxide ions undergo an oxidation reaction and give up electrons to the anode to complete the circuit and form water and oxygen gas:
Anode(oxidation) : 2H2O(l) ---> O2(g) + 4H+(aq) + 4e-
hence decomposing water into Oxygen and Hydrogen;
Overall reaction : 2H2O(l) ---> 2H2(g) + O2(g)

The volume of hydrogen gas produced is therefore twice the amount of oxygen gas. Assuming equal temperature and pressure for both gases, the hydrogen gas has twice the volume of the oxygen.

Answer 3

Yes!!!
When water is placed in the 'H' pattern reaction vessel together with a few drops of sulphuric acid to provide H+ ions to set the system going.
An electric current is passed through water and hydrogen and oxygen are given off. providing the electrodes are correctly positioned one each in each 'leg' of the 'H' reaction vessel hydrogen will be released into one 'leg' and oxygen into the other 'leg'.
Twice as much hydrogen is produced than oxygen, hence the chemical formula is H2O.

Answer 4

the technique is electrolysis: separation of water(H20) into hydrogen and oxygen gas, is accomplished by making use of passing direct contemporary from a battery or different DC skill grant with the aid of a cup of water. it is likewise possible to take a reactive steel plus with acid to offer Hydrogen and salt. Use Mg , Al or Zn (steel) HCl , HNo3 , H2 So4...(acid)
