Turn Water to Hydrogen

Introduction to turn Water to Hydrogen

There is a close relationship between electricity and chemical reactions. The relationship is reflected in the fact that an electric current involves flow of electrons. The electrons which produce an electric current are no different from the electrons which exist in atoms and take part in the regrouping of the atoms of the reactants in chemical reactions. So it is not surprising that some chemical reactions can produce electricity and conversely, electricity can produce certain chemical changes. The decomposition of a substance by passing a direct current of electricity through it is called electrolysis.

Turn Water to Hydrogen : Water as an Electrolyte


Water can only conduct electricity when it is electrovalent in nature. Pure water such as distilled water, or molten lead bromide are covalent in nature. Such electrolytes are called as non electrolytes. Pure water when added with sodium chloride or sugar conducts electricity. These types of compounds which conduct electric current and are decomposed by it are called electrolytes.

In pure water only one molecule in ten million is split into H+ and OH- ions. Here H+ is called the cat ion and OH- anion. The electrical conductivity of water arising from these ions is very small, but measurable. Acidified water i.e. by adding a small quantity of sulphuric acid can be effectively ionized into H+ and OH-. The electrolysis can be carried in the presence of platinum electrode.

Turning Water to Hydrogen : Results


The results of the electrolysis are given as:

Two volumes of hydrogen produced at the cathode
One volume of oxygen at the anode
A decrease in the concentration of sulphuric acid at the cathode
An increase in the concentration of sulphuric acid at the anode
The total weight of sulphuric acid remains constant. So the net result is that only water is decomposed. The electrolysis of acidified water may therefore represented as:

2H2O + electrical energy = 2H2 + O2
