Cations (positive ions) are attracted to the cathode (negative electrode). Anions (negative ions) are attracted to the Anode (positive electrode). I guess it's easier to remember when you think about it from this perspective

This is so helpful thank you! I just have a question. When I learnt this at school, we were taught that the cathode is the cell lining in a steel case but when I have come to revise, my revision guide and here is different. I was just a little confused about which one I should learn and if a question came up on the test which way would I explain it? I also just want to say thank you so much!! You have helped me so much so far and I will be definitely rely on these videos when it comes to next year :)

OIL RIG oxidation is loss (of electrons) Reduction is gain (of electrons

[@kage2kx]

Maybe you should do like a full revision guide for 3 Science Subjects; Physics, Biology, Chemistry!!!

[@irinakuznetsova3739]

I have a question- why do we need to double the equations? (3:35) and do I need to double the equations in the exam?

[@Freesciencelessons]

We need to double the equations because the gases produced (eg Cl2, O2, H2) are all diatomic molecules (ie have two atoms in the molecule). So we cannot show the equation for just one atom as that would be inaccurate. You would be expected to double the equation in the exam.

[@Freesciencelessons]

I'm glad that my videos are helping.

[@owaisali8344]

How do we know the charge on each atom

[@Freesciencelessons]

Group 1 ions have a 1+ charge and group 2 ions have a 2+ charge. The aluminium ion is 3+. Group 6 non-metal ions have a 2- charge. Group 7 non-metal ions have a 1- charge. Any other ion that you need for these type of question will be given.

[@garvick20]

Sir ...Great video. Can you please clarify (with an explanation) if this reaction is exothermic or endothermic? Thank you.

[@rashan6681]

Electrolysis is endothermic because it requires energy from the surroundings, he states it in one of his videos

[@chipapao3662]

thank you sir

[@Freesciencelessons]

No problem and thank you for the comment. I appreciate it.

[@chasladhar1774]

Freesciencelessons would electrolysis be the same for copper sulfate to extract a pure sample?

[@everythingtv4875]

will we be given the ions or do we just have to know it? Thanks !

[@Freesciencelessons]

You are meant to know aluminium oxide but for other ionic compounds you should be given the ions (or enough information to work them out).

[@olliepollie9732]

na g

[@joshphillips3171]

probably not, you can possibly say something like how the cathode is negatively charged and the aluminium being positively charged therefore they're attracted to each other and in doing so, separates the aluminium from the oxygen
