Interpretation: The equation for the decomposition of water by
Concept Introduction: In an
Explanation of Solution
In the electrolysis of water, two electrodes are immersed in pure water. Here, a small amount of electrolytes such as sulphuric acid or potassium nitrate is added to pure water. The solution conducts
Thus, the
Oxidation:
Reduction:
In this process, the anode region turns acidic due to an increase in hydrogen ions. On the other hand, the cathode region turns basic as the number of hydroxide ions increases. The above two reactions can be added to get the overall cell reaction:
Therefore, the equation for the decomposition of water by electrolysis is as follows:
