Dear Sir, thank you for the insightful video. Getting ready for O-levels amidst the COVID-19 scare in 2020. I have a question. At 9:50 you have drawn the small battery in which the electrons are moving from the positive to the negative according to the arrows. However, in the circuit you have labelled the arrows moving from negative to positive. Which one is correct?

Hi Angelino, I supposed you are talking about the "small red battery" which i drew. That is used to help us decide the charges of the two electrodes. Everything presented in the video is correct. Note that one of the application of Simple Cells is in Batteries and you learn in basic Physics/Science classes (Sec 1/2 if you are based in Singapore) that electrons always travel out of the negative terminal of the battery, and returns back at the positive terminal. Hope this is clearer to you now. You can visit my Basic Chemistry blog www.SimpleChemConcepts.com (written based on GCE O-Level Pure Chemistry and IP Chemistry syllabus content) for more tips and discussion of Chemistry concepts). Meanwhile, stay safe and continue to learn with understanding. All the best for your upcoming O-Level examination. To Your Academic Success in Chemistry, Sean Chua

hello, thank you for your video! may I ask if the anode in simple cells will always discharge/oxidise, since the metal at the anode is always more reactive than the cathode? thanks!

so good, make really sense. however, some points you should points out that may confuse some student with poor basic knowledge about the electrolysis. for instance, the rule of production at the electrodes, why hydrogen is produced and chlorine is produced

Hi Kira. Good to know that you find the video useful towards your learning. However, it seems like you are still not very clear about Simple Cells. Based on your comment, it seems like you are confused between Simple Cells and Electrolytic Cells. They work differently. The term "electrolysis" means the use of electricity to electricity to decompose an electrolyte. Also, this video is meant for students taking basic Chemistry syllabus such as GCE O-Level Pure Chemistry in Singapore. Note that it does not comprehensively show all the intricate details on how the Simple Cells work. If you would like to find out more about Electrolytic Cells and Simple Cells at this basic level, you can read my blog posts or watch my videos at www.simplechemconcepts.com/videos/ Note: Chlorine is not produced in this particular simple cell. The" actual" details on how the cells work are only discussed when we learn more advanced concepts in Advanced Chemistry syllabus such as the GCE A-Level H2 Chemistry syllabus in Singapore. Over there, we will use something called Standard Electrode Potentials to discuss the redox reactions involved in both the Electrolytic Cells and Simple Cells. For anyone who is interested to find out more about the strategies and concepts in Advanced Chemistry, do visit my blog www.ALevelH2Chemistry.com. Do continue to learn Chemistry with understanding, Sean Chua | WinnersEducation.com

Hi Sughra Zulfiqar, this is a very good question. Many students are confused between Simple Cells (also known as Galvanic Cells, Electric Cells and Voltaic Cells) and Electrolytic Cells. The charges on the cathode and anode for the two different cells are different/opposite. For Simple Cells: Cathode (+) and Anode (-) For Electrolytic Cells: Cathode (-) and Anode (+) Students are confused because they tend to just memorise and regurgitate, instead of understanding the underlying concepts on how they work. For Simple Cells, it involve spontaneous reaction whereby Chemical Energy is being converted into Electrical Energy. For Electrolytic Cells, it involve non-spontaneous reaction whereby Electrical Energy is being converted into Chemical Energy. You can refer to the blog posts and videos on my Basic Chemistry website www.simplechemconcepts.com/?s=electrolysis to understand more about how each type of cells work as well as their similarities/differences. There's quite a number of strategies and analogies/mnemonics which i shared in my blog. To Your Chemistry Success, Sean Chua

Why don’t the electrons from zinc directly reduce the H+ ions?
@SimpleChemConcepts
4 жыл бұрын
It did. Zinc loses electrons [oxidation occurs]. H+ ions gain electrons [reduction occurs]. Redox Reaction occurs whereby both oxidation and reduction occurs simultaneously in a Simple Cell. It is a spontaneous reaction.

Electrolyte no copper ions to be discharged. Only positive sodium and hydrogen, and since hydrogen is lower in the series, it is selectively discharged. If electrolyte is aq copper chloride, then copper will be discharged.
