IGCSE Chemistry : Electrolysis

For a set of notes to go with this video, go to www.scribd.com/ChemistryKlipz
This video covers the vocabulary used in electrolysis, how the process works, and how to work out what the products will be when doing electrolysis of ionic compounds when molten, and when in solution. Half-equations are also covered. Finally we look at the chloralkali industry as a specific example of use of electrolysis in industry.

Thanks man you kept our 3 week chemistry class into this short video ..........respect dude

[@THExxDEATHxxxDEALER]

Hey man Thanks for this !! Well done and Beautifully explained ...Doing my IGCSE here in Sri Lanka , and had trouble remembering this process.... that is , Untill I found This ! Thanks Again !.

[@S_H_33]

mate, you are a legend!!! FINALLY i understand bloody electrolysis, thanks again, great video, very clear yet detailed ;)

Greatly appreciated

Hi Patty
It depends on the relative concentration of the chloride ions and the hydroxide ions in the solution. If chloride ions are present in the solution at reasonable concentration they are going to be oxidised more readily than hydroxide ions - that's why electrolysis of NaCl(aq) produces chlorine gas at one electrode and hydrogen gas at the other (leaving sodium hydroxide in solution). If there are very few chloride ions present, then you could get the hydroxide ions being oxidised to oxygen and water.

[@fateshow5303]

thanks, our science teacher is so crappy he didn't even tell us that the positive and negative atoms were in the electrolyte. I just knew that one was a cathode, the other anode and one gets attracted to the other. However he told me that they travelled through the electrolyte, which is why I always wondered why they were joined at the top. -he didn't answer my question when I asked him

[@izzyp7033]

What's the difference when a solution is electrolysed with different electrode materials? For example, when Copper(II) sulfate is electrolysed using a platinum or copper electrode. What's the difference?

there are only 3 years in IGCSE

[@alooshemo619]

[@pattymananavicphol3150]

Aren't hydroxide ions give up electrons more readily than chlorines ions? Take the electrolysis of NaCl as the example, the OH ions discharged to form water and oxygen, instead of Cl ions. So I don't get it why in the case of electrolysis of LiCl, Cl ions are being discharged instead of OH.

[@messi102882]

water is a covalent compound and it can be split up using this method?

[@Meow-ym5rh]

Lithium wasn't there in the reactivity series how do we know it's more reactive than hydrogen? :/

[@2yoil]

if you do a quick Google search you can find a table that shows the reactivity of all the elements.

I think that instead of steel,nickel is used as the cathode.

[@LinhVu-oy9gl]

Why does the Copper have the valency of +2 even though it is in group 11?

[@NeoNik21]

+Linh Vu It is a transition element. They have variable oxidisation states. So, copper can be +1, +2 or +3. But in our syllabus it's only +2. Exams in may xP
