O-Level Chemistry . IP Chemistry: Selective Discharge of Ions in Electrolytic Cells – Part 2

#seanchuachemistry #olevelchemistry #ipchemistry

In the previous video, we have looked at the three factors which will decide on the ions that are being preferentially discharged when an inert electrode is being used, namely:

1) Selective Discharge of Cations

2) Selective Discharge of Anions

3) Effect of Concentration on the Selective Discharge of Anions


Today, we will look at the last factor (Nature of Electrodes) when it comes to selective discharge of ions in electrolysis.



In this video, we will compare the electrolysis of copper (II) sulfate solution using two different types of electrodes: Inert Electrodes and Reactive Electrodes.



The concept will be explained in a step-by-step manner using the examples given and you will see the difference in the products formed at the end of electrolysis.



All these 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. Most of them have went on to Score their A-grade in Chemistry Exam over the last 19 years!
