In this blog post, we take a look at the difference in the reactions that occur and the products obtained when different types of electrolytes are used. We will use inert platinum electrodes and 3 different sodium chloride electrolytes for the discussion.
The electrolytes are:
- Molten Sodium Chloride
- Dilute Sodium Chloride Solution
- Concentrated Sodium Chloride Solution
The 3 factors involved in the selective discharge of ions with inert electrodes:
- Selective Discharge of Cations
- Selective Discharge of Anions
- Effect of Concentration on the Selective Discharge of Anions
We have gone through the basic concepts involved previously in another blog post. If you have missed out on it, you should go and watch it first.
Note that the use of reactive electrodes will make the reactions more complicated. You can take a look at my other video to learn them also.
All the video tutorials are based on what we share with our Secondary 4 GCE O-Level Pure Chemistry and IP Chemistry students in our weekly Sec 4 Pure Chemistry Tuition Classes.

In the YouTube Video below, you will learn in a step-by-step manner on how different reactions will occur at the electrodes when different sodium chloride electrolytes are being electrolysed in an electrolytic cell.
