The thick rod of impure copper plate is to be attached to the positive terminal of the battery because when electric current is passed through the copper sulphate solution, it gets dissociated into copper and sulphate. The free copper, being positively charged, gets drawn to the negative terminal of the battery and gets deposited on it. On the other hand the loss of copper from the solution is regained from the impure copper rod which is attached to the positive terminal of the battery.
ANS: Thick plate. The positive ions from thick plate will be deposited on the thin negative plate. Thus, Postive terminal should be given thick.
😂😂😂😂
Hw answer= The thick plate of impure copper should be attached to the positive terminal of the of the battery and the thin plate of pure copper on the negative terminal because the froom the impure copper plate the copper will leave and get deposited on the thin plate of pure copper , thus leaving behind only the impurities and also the purification of copper happens .
Thanks for this session looking forward for such amazing videos .
I can't understand why the get like by saying who is here before exam
The thick plate of impure copper should be placed at the positive terminal and the thin plate of pure copper should be made the cathode because during electrolysis the pure copper from the anode will get deposited on the cathode . Hence ,we will get pure copper.
Anode is positive.
A thick rod of impure copper should be connected to the anode and the thin plate of copper should be connected to the cathode this is because of refining. In refining the impure metals get connected to the anode.
This is because the some amount of pure copper gets deposited to the cathode and impurities remain on the anode.
A thick rod of impure copper should be connected to the anode and the thin plate of copper should be connected to the cathode this is because of refining . In refining the impure metals gets connected to the anode
This is because the some amount of pure copper gets deposited to the cathode and impurities get remained on the anode
we have given that the copper ions are transferred to the thin copper plate, then the thin pure copper plate must be connected to the negative terminal of the battery. In this case the other electrode that is impure copper rod must be connected to the positive terminal of the battery.
Hw Que Ans-The thick plate of impure copper should be placed at the positive terminal and the thin plate of pure copper should be made the cathode because during electrolysis the pure copper from the anode will get deposited on the cathode . Hence ,we will get pure copper.
Thick plate of impure copper will become anode and thin plate of pure copper will become cathode
6:36 Sir i have a doubt , you said that s compass 🧭 have plastic cover but sir pulatic is inslutor so how the compass neddle can move.
There is a small magnet needle inside the plastic outside of compass. Due to magnetic effect of electric current, it moves and shows deflection.
The thick rod sould be connected to anode....sir plss also mention the answer of hw question in video/comment.
Thanks sir, it helped me a lot because I was watching this video at 1:37 am and my exam was at 2:00 pm, this video helped me a lot , I got good sleep and gave the exam easily😃😃😃
Who realises that 1:37 am
is dawn time lol.
Homework questions
The electrode that is impure copper must be connected to the positive terminal of the battery because the copper ions get attacted from positive terminal to negative terminal .
well explanation ❤❤
The thick rod of impur copper will be attached to the positive terminal because the positive terminal gets attracted to negative terminal and the impurities of the impure copper gets deposited on the pure form of copper. And the impure copper becomes pure copper.
😁 thanks for the information 🙏
the homework question's answer will be this:
The thick rod of Copper will be the Anode and also will be attached to the positive terminal of the battery
and...
thank you so much sir for the revision😇
Sir can we charge mobile phones by using potatoes
Sir thanks for teaching
I got 77 out of 80
Sir very satisfied by your way of teaching.....🎉🎉🎉
I got 80 out of 80 in science
Byjus is best
The copper with the impure substances should be attached to the anode as the copper metal of the anode would be deposited to the copper metal in the anode, thus in a way filtering the copper from the impurities.
what if we use finger instead of cathode
very beneficial for revision for boards
❤
sir please teach the chapter 12 some natural phenomena because it is a very conjusted chapter i can't understand it
I like your choice of words, "conjusted" instead of confusing. Nice vocabulary bhai
2nd comment❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Bruh are you here to study or do this nonsense
thankyou sm byjus
14:44 sir if this is electroplating then what is galvanization aren't they same
Check pg 179 last paragraph. Galvanization is one application of electroplating.
@@simplykass thanks
Hi sir
Impure copper will be on positive terminal
Hello sir my name is Avinash thanks for giving us your very precious time

Impure copper should be attached to the positive terminal of battery

how it is possible the video is showing 2 weeks ago and your comment is showing 3 weeks ago
Coz.this video is already posted before and started after and I have comment before and the video is showing the time in which this video is done....

Sourabh Sir's explanation is incredible!
Who else agrees? 🙋♀🙋♂
Who is here before exam 😂😂
Myself present 😂😂
Meee...
Please only talk English otherwise mention in the caption as Hindi explanation 😠😠😠😠😠😠😠😠😠😠😠😠😠😠😠😠
I agree but this is not only for those who knows Hindi there are many those who don't know...
You should know English
