Pov our chemistry teacher sended this
grammar 1000%
@@nicholashouse1613 bruh u understood the message, thats enough. having perfect grammar aint necessary
@@nicholashouse1613 what do u expect from a student who doesnt have decent teachers who just send youtube videos instead of teaching nicholas??

My chemistry teacher from Udvash, Bangladesh sent me this video so that we could visualize the process . Thank you Mr. TH-camR for making this video and teacher of Udvash for sending us this video .
You are most welcome 💜
মিফতাহুল জান্নাত,আমিও উদ্ভাসে পড়ি;এই ভিডিটা দেখেছি।
আমার একটা প্রশ্ন ছিলো, তুমি কি উদ্ভাসের উইকলি এক্সামটা দিয়েছো?
উইকলি এক্সামটা কি সকাল 09:00 থেকে রাত 09:00 পর্যন্ত ছিলো?
@@shammeakter1193 which class are you in?
The houra sound when the light goes on was so unexpected XDDDDD
thanks a lot, the video was really helpful !
Glad it helped!
Thank you very much. This video was indeed helpful. I never thought that I'd be able to comprehend this part of electrolysis.
You are most welcome! Glad it was helpful!
honestly luv this video !
Finally, I found the perfect vid on youtube explaining this chapter
Glad you hear it 🙂
Sir thank tou very much, my school book has soo much detail that its confusing and slow, but you just summarized everything in the refining of copper
I've watched three vidoes of your channel so far and I've thoroughly understood these concepts.
keep up the great explanations!!
Great to hear! Thank you so much!
Excellent video!.
Very helpful
Okay lah daripada x faham langsung;)thanks
thank you so much.....☺
Great video! Really helped my revision!
Glad it helped!
I perfectly understood yr what a great way love your skills
Thank you so much!
I thank you loads,FUSE SCHOOL!!!
Most welcome 🤗
So if you wanted a purify everything in the impure solution would you have to know all the impure metals and then create a cell where you remove the most reactive metals first?
dude your question is so confusing.
Yes and no. It does work for a lot of metals, but not all. So long as it's a non-ferrous metal like aluminum, copper, zinc, lead, titanium, rare earth metals, any precious metals, alkali metals, hell it can even used to refine nuclear fuel. There are some specific cases were it only works in the extraction part and not the deposition (like nickel, once it's in the electrolyte it has to be chemically refined out), but so long as you've got an appropriate electrolyte it should be possible. Btw there are a lot of easy electrolytes to use but most often its sulfides (copper, cobalt, nickel, zinc, and silver come to mind) but that's far from an exhaustive list. The only thing that's important is that there are ions of what you want to extract present, so aqueous salt solutions are the usual go to but others, including molten salts, can be used.
In short, its widely applicable but does need to be specific to each situation. And if I'm understanding your question correctly (that you want to purify metals in one solution sequentially) then it's possible but not optimal. You could do copper until the zinc content got too high then swapped the copper cathode for a zinc one and continue and so on, but it would be suboptimal
Very nice concept videos by fuse school 😆😆
educative!!
Fantastic. That’s going to be experiment no 2 for my junior high schoolers here in Japan!
Awesome!
Pretty cool.
We are literally in class and were told to watch your video and understood everything thank you very much for the video😊😊😊😊😊
Glad to hear that!
Thank youuu this further my understanding!!! Also assists me to accomplish my chemistry assessment
Most welcome! Glad it is helpful!
Excellent video. How long does the electrolysis process take for example, if the anode is 1lb? How do you test the concentration of zinc ions in the solution? Are there signs that the solution is over saturated with zinc ions?
sjagain no,
Thanks! This was really useful, much moreso than a textbook. :) #appreciated
Glad it was useful!
Hi thanks for the video! Why is it that the anode turns into sludge exactly, thanks.
Very cool
Can you please tell me how the anode sludge is recovered for silver or gold? can these be electrorefined again?
I appreciate so much
The video was helpful
Glad you found it helpful!
Awesome Video Dudes and Dudettes
Thanks!
What if I use brass as anode? Can I extract the copper this way or will zinc also travel to the cathode?
this helped me alot
Glad it helped!
Wonderful video...
I can't explain how great this channel is..
Keep it up
Thank you very much! So nice of you 🙂
Thanks it was helpful. 😁👍
No problem 👍 Glad it was helpful!
Wow nice sir, thanks a lot for your video
You are very welcome!
Nice
Can we refine brass scrap to separate copper and zinc ?
thnx
How is potash formed?
I literally love you
🤗💜
Thank you sir
You're welcome!
Why do we necessarily need Copper's salt , if the anode can get its electrons transferred to pure cathode , attracting the Cu2+ ions from the impure copper it?
Wow ,
U R perfect 👌🏻
🤩🤩🤩🤩
Thank you 💜
aha! finally after 3days of searching for that "gold is collected below anode"
Who can answer this question.
If i was running material that is 60% cu and 39% zinc how could i win out the zink could i use a titanium anode/ or platinum anode and a zinc cathode? Im curious because of the amount if zinc how i could pull it out if solution quickly and efficiently
Excellent.
Why zn cation not deposited at cathode to get discharged
Cu ions have more ability to get deposited on the cathode. Therefore, Zn is left out in the electrolyte.
Thanks
No problem
At the last example, if you use Na instead of Mg, does it blow up? Thanks 4 the video and answer to my question
No it won't blow up. Instead the Na ions will dissolve in the solution making Na2SO4
Soo, what's the role of the copper sulfate in this experiment? Aren't the copper cations from the solution the exact ones that are reduced by the cathode and therefore turned into pure copper on the surface of the cathode?
Good question. Copper ions (+ve) can only form at the anode if there are negative anions (the sulphate ion, in this case) to balance the charge. The sulphate ions (which don't get used up) are there to stabilise the copper ions in solutions from when they are formed from the impure copper anode and deposited as copper on the pure cathode.
@@fuseschool Thank you greatly !
thanks
No problem
Is there a way to precipitate out or otherwise remove the Zinc from the copper sulfate solution?
Yes, but it's another process.
so when the cu anode ionises, the cu ions from anode moves to solution .
the cu ions from solution moves to the cu cathode ? is tht rght ? please help im confused
Right
Yes that is correct. The aqueous solution contains Cu ions from the anode which are then deposited on the cathode.
oh i get it. Gold and silver and totally unreactive, while copper is still able to react. If a more reactive metal was to be in impure copper at the anode, like zinc, it would be discharged right after copper since copper is less reactive and gets prefentially discharged.
will this occur with copper acetate electrolyte?
Sir plzz improve sound quality ....otherwise your explanation is fab😊😇
Thanks! And noted!
explain voltage and amp?Thanks
gold and silver are less reactive than copper, so wont they get preferentially discharged to copper? Its just like how copper is less reactive than hydrogen in aq solution and how copper gets discharged preferentially to hydrogen.
Niccccceeeee
Thanks sir this really helped with my studies . From Fiji
Glad to hear that it helped!
Wow this was amazing thanks
You're so welcome! 😊
Nice video
Thanks!
The question is..... if you purify copper with purified copper... where did the first purified copper come from to do this electrolysis? Was there a holy purely piece of copper existing in nature?
there was probably a more expensive way they purified it before electrolysis was discovered
Did the electrons move from the anode to the cathode
+to- positive to negative
What happens to the OH (hydroxide) in the solution??? Why is not oxygen formed at the anode???
Depends on the voltage. It would be a waste of current and water if it's high enough to release oxygen.
Why aren't impurities like Zn²+ and Fe²+ go to the cathode because of electric force?
Well, Cu ions have more tendency to accept electrons and get deposited in the cathode. That's why the Zn and Fe impurities do not get deposited.
2:22 does anyone know why the concentration of copper in it stays the same? instead of getting attracted to the pure copper Anode.
Remember that the anode is made of impure copper. So as much copper dissolves there - as is deposited on the cathode, keeping the concentration in the solution constant.
What if I put impure copper at cathode and pure copper at anode. Will the purification still occur ???
Remember always that at anode only oxidation (removal of electrons) take place whereas at cathode (addition if electrons) take place. So in your case, the purification cannot happen.
So beautiful 💞💞 thank you
Thank you too! 😊
Its cute☺
😊
why did the anode get smaller
And what happened to the SO4²-ion?Please explain.
The concentration of CuSO4 remains constant I.e the electrolyte concentration remains the same.
I am confused. The way I see it, the desired reaction would be spontaneous because in the solution surrounding the pure copper the concentration of copper ions is greater.
Yes, but in order to obtain the impure copper ions from the anode, one must supply external electical energy so that the ions are discharged and can move towards the pure cathode.
Hi, I have a doubt why should we add dilute sulfuric acid to the electrolyte to make it acidified??
How can we Reduction of Anode Mud ?
It is another process where the anode mud is refined to extract precious metals.
Peace! My chemistry book says the copper(II) sulfate solution is acidified. Why is that?
Copper sulphate is a salt of a strong acid, H2SO4, and a weak base, Cu(OH)2. So in aqueous solution, the Cu2+ ions undergo hydrolysis:
Cu(2+) + H2O --> CuOH(+) + H(+)
The release of H+ ions by hydrolysis makes the solution distinctly acidic.
@@fuseschool Peace! Ok, so we are not adding an acid. Rather, the solution itself is acidic. Is that what you mean?
Why the cathode should be pure?
If a pure copper sheet is required to purify the other copper sheet how’d you get a pure copper sheet in the first place?
The anode is made of IMPURE copper - listen carefully at 0:46
sir, what would happen when you switch the polarities, meaning the impure one becomes the anode and the pure one becomes the cathode.
the second question is why do we have to use a copper electrolyte and can't use anything else?
Not quite true Intro.....smelted copper commanded a 15% premium over electrolysis copper, due to its superior quality for electrical wire.
dont get the oxidation and why the copper moves
The anode is positive and the cathode is negative. The copper ions in the anode are positively charged and so they are attracted to the negative cathode (via the copper sulphate electrolyte solution).
At the negative cathode, the positive copper ions gain electrons which is called reduction. The copper is then deposited onto the cathode.
At the positive anode, electrons are lost - which is the oxidation.
Does this help?
yeah thank you sir :)
FuseSchool - Global Education so why do we use copper sulfate????
if you are reading my comment pause the video and think
Lol Samuel miguel
Pls tell I confused
If electrolysis is necessary to get purified copper where does the pure "cathode" come from... Also ions fall under the category of theoretical physics in atomic THEORY. 🤪
The "pure cathode" is obtained from the previous refining. And ions are unstable species, they undergo chemical reactions to attain stability, thus iONS are included in chemistry.

Hi
Hey!
No.... I learned that anode is negative and cathode/cation is positive
