Predicting Products of Electrolysis (Molten and Aqueous) - GCSE Chemistry Revision

Hi everyone,

I hope this video helps you to feel more confident with identifying the products of electrolysis for molten and aqueous electrolytes. Which GCSE Chemistry/Science topics do you want to see next?

Really helpful video - loved it. I've been struggling with electrolysis since year 10 (am in year 11 now) but this really helped. However for the predictions of the reactants at the cathode, it's more accurate to say "either hydrogen or the metal will be produced whichever one is less reactive *unless* the solution is molten". Thanks!

I can't believe this brilliant video has less than five thousand views even after two years. What are people watching if not this.

You explained this better then any other YouTuber and my teacher. Thanks

me: gets the first practice question right
me: immediately subscribes halfway through the video

I know you're not reading but you just helped someone become an electrical engineer. TYSM. I don't know how to appreciate you. it might seem a bit weird but trust me, you helped me a lot. LOVE YOUU

This video explained electrolysis in 14 minutes better than my teacher explained it in like 2 hours💀

Miss Wetton when I get an A* in my finals I'm coming to donate to this channel, definitely my life saver

[PoppyMurphy-zj]

Thank you so much! This makes so much more sense now

[stuartwilkie]

Thanks so much for explaining this. I was so frustrated in class that I didn't know what was going on! When I saw this I realized there are fairly simple rules to it. Thanks again!

[salmamahmoudibrahim]

this has helped me so much as i was really confused on how to find out the products of thank you os much for taking the time and effort to do this <3 <3 <3

Got a chemistry test tomorrow and this really helped!

@Youssef Remember the more negative the electrode potential is, the more difficult it is to reduce, so the easier it is to oxidize, the halogens have a more negative electrode potential so their ions are more easily oxidized in to their standard states than oxygen is. So the halogens would be released rather than oxygen when they're present. I hope this makes sense.

[hannahhernandez-rodriguez]

brilliant, really broken it down in a simple and comprehensible manner. Thank you :))

"oxygen is produced unless there is a group 7 element". The production of oxygen from OH- has oxidation potential of -0.40V, which is higher than group 7 element oxidations such as that of fluorine ion (-2.87V), chlorine ion (-1.36V), bromine ion (-1.09V), iodine ion (-0.54V). Therefore, wouldn't oxygen be more likely to be produced even in the presence of such group 7 elements?

Teacher you are awesome 💯. I was so stressed about these questions 😫 but now i am relieved 😅😅❤

Why is cl2 produced in the electrolysis of molten sodium chloride? I thought it had a negative 1 charge
sorry I'm dumb

[chemmy]

So this is all I have to know about electrolysis or are there more?

[hsleuud]

8:59 why is h2 produced because for the others it’s just the atom without a number, i thought it turns back to a singular atom

[ChickenNCheese.]

Is anyone else confuse, cause at least in my syllabus, the products (at anode) for a diluted and concentrated aqueous solution will be different. If its a concentrated aqueous solution, the product is a halide but if it is diluted the product would be a OH (oxygen is released) please help

[eshajohal]

will the reactivity series be given to us in mocks/exams etc?
