you are a very good teacher, and coming from a grammar school that says a lot, keep making vdeos and thank you very much for helping me get 100% in my electrolysis test
I’m in the ninth and my exams are next year this topic was a bit confusing for me and I just took my assignment sheet and then opened up RU-vid and searched for electrolysis and you came up thank god I saw your channel
I've learnt more from you as a teacher, than I have in my nearly 12 years at school (including primary) wish I had known about this channel last year!! :)
Thanks so much! I'm only in year 10 but in my mocks I managed to pass all of my sciences thanks to you. In chemistry and physics I got grade 6 and in my biology I got a grade 5, not the best but I'm sure I would've failed without your help. I'm confident that I'll manage to improve as I carry on watching your videos. Science is my worst subject but I'm so much better now, and I've got you to thank for that.
Great video, thanks a lot! Few questions though: 1) What about electrolysis of sodium chloride solutions? 2) What about electrolysis for sodium hydroxide/sulfuric acid? 3) What about electrolysis for nitric/hydrochloric acid? Is it the same as 2)?
Thank you very much, Mr. Thornton! This video has really helped me a lot! What my Chemistry teacher in school tried to teach, you showed me how to do it in less than 15 minutes! Great explanation and very easy to understand!
Not at all! Remember, these videos are aimed at 14-16 year olds who've *already* been taught this stuff once. There's a whole load of topics you haven't yet covered which all build up to this, and even then this is only relevant to people aiming for the highest grades at GCSE! Give yourself another three years; you'll have built up way more background knowledge and it'll seem much easier 🙂
Christopher Thornton i was really upset when i found out that the owner of mygscescience.com privatised his additional videos on youtube and the olny way to watch them was to subscribe to unfair amount of fee i especially needed help on addtional and now you have given it! im suprised many people havent noticed this thank you for your help i have a chemistry exam on thursday im still not entierly confident biology is my strongest
your electrolysis videos have actually helped me so much, much teacher has literally tried to explain it to me about 20 times and I still just couldn't get my head around it until I watched these videos! so thank you!
your videos are really helpful but would you mind covering, isotopes, polymers, chemical analysis and instrumental methods, rates of reaction, collision theory, energy transfer in reactions, acids reacting with metals, oxides, hydroxides and ammonia and making salts because I also need to cover these for my exams thanks
Becky Bentley Polymers is already on my to-do list, and I'm working my way towards it. It's one of my more requested topics, so I'm going to prioritise it. I'm planning on doing two videos - one covering the basics from C1, and one covering how the structure of the polymers affects their properties (including the one higher tier bit about explaining these properties in terms of intermolecular forces). Thanks for the request!
Your videos are so so helpful:) Thank you so much for taking the time to do them! Could you please do some Further Chemistry videos as soon as possible? (Triple award) I have my exam in two weeks and am really bad at most of the topics:( Thanks!
+Christopher Thornton Can you please make a video, which differentiates between the Electrolysis of Brine and aqueous NaCl. Please Include all Half- Equations and explain all the theory part. I would really appreciate it sir! Thank you! Please do confirm about by when they will be here, if you agree.
hi mr thorton did you do the video on ionic equations...remember i asked you couple of months ago? you said ionic and half equations are slightly different from each other...and you said that you will do the video on ionic equations
I'll add it to my list, but you might find these videos on polymers useful in the meantime: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DmhOTGZqZUk.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Qp0tzZ07Ivs.html
My chemistry exam is tomorrow and did not know how to do half equation thanks soooo much Just a question would the empirical formula be on a C2 higher paper ? Or is it just on foundation
So when it is a positive ion, do you put the electrons on the left hand side and when it is a negative ion, on the right? Im a bit confused as to when you put electrons on the right or left hand side of the equation? Many thanks though your videos are very useful
How I remember it is that since positive ions attracted to the negative electrode then the e- will be on right, because the right side is usually associated with positive things( if that makes sense) it's the 'positive way" so therefore the e- is on the 'right side' NaCL and brine are the Same thing in terms of this GCSE. Brine is just salt dissolved in water. NaCL is simply just salt. But since NaCL doesn't conduct in its salt form it has to be dissolved in water, therefore making it brine.
+Science Fanatic Still a bit confused but thanks for your help Just thought, when it is oxidation, so they are losing electrons do they appear on the right But when is is reduction, so they are gaining electrons they appear on the left? SO CONFUSED Sir we need your help!!!
+bob john Actually, I'm not sure you do need my help, because in both your comments you've got it exactly right ☺ If anything, by thinking about it in terms of oxidation and reduction, and gaining or losing electrons, you're actually developing a deeper understanding than is necessary if all you want to do is complete the equation. Do you still feel confused?
+Christopher Thornton Thank you! Its just because in the syllabus, it shows 2 different ways of writing half equations when it is oxidation But my teacher prefers it when the electrons are on the right hand side for oxidation and left for reduction Just to confirm is that right??
+bob john Yes. It's a bit like writing 4 = 3 + 1 compared to 4 - 1 = 3. You are, after all, basically doing addition and subtraction with electrons. Either is correct.
Can you not put the electron on either side of the equation but just switch it from adding an electron to subtracting an electron depending on which side it is put?
Yes, that would be valid actually, and it depends on the exam board as to whether they do this or not. It's a bit like either writing 4 - 1 = 3 or 4 = 3 + 1 (where the 1 is the electron) - both are valid and balanced.
Kathy Hawkins At this time the app is only on Android, and still under development for that platform. As you might imagine, developing apps, even simple ones, can be quite a lengthy process, especially when the development team is just me (and I'm also working a full-time teaching job, making these videos, and developing the Snapquiz website too!).I'd love to be able to offer the app on iOS too, and intend to at some point in the future, but unfortunately that's not going to be before this year's exams. Sorry, but there are only so many hours in the day :(
Hi! Like your videos, they're very useful. Do you think you could please cover enthalpy, calorimetry calculations, as well as energy transfers? Thank you very much!
+Haroon g3ood I'll add it to my list, though you might find this video on bonding useful in the meantime: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IH_wnJ49Ev4.html
Hi Good Morning to you!! Do you teach AL Science such as Chemistry, Physics or Biology?? If yes can you let me know please whether you have any videos or DVDs or CDs. I would love to buy them..
Yes, please check out my main channel page ru-vid.com and scroll down to see playlists for all the sciences. I don't have any CDs or DVDs, but I do have an ebook which can be downloaded for Kindle here: www.amazon.co.uk/-/e/B01BBTP986 This summer I am going to be working on the next ebook as well. Thanks for your comment!
So I understand that you must balance and add electrons to make it an atom... But I don't understand why you add to different sides depending on the question? Like why sometimes did you add/remove electrons before the arrow and sometimes after...someone please help?!?!
Its because you either need electrons to make the atom (cations), in which case it's before the arrow, or you need to lose electrons to make the atom (anions), in which case its after the arrow, as free electrons are the product. If we look at chlorine, he added the electrons onto the right side. You could also write that you minus it from the left side, but adding it to the other side is a much better thing to do.
We're doing this and I'm in year 10, I'm probably going to fail chemistry as well as the other sciences, I just don't understand anything and I have a really low target for them aswell
The trick is to stick with it, get one concept clear in your head at a time, and keep your chin up. Targets are a minimum to aim for; there's nothing stopping you aiming higher. Next test you have, aim to ace at least *one* concept, and build from there :)
