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 .

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.
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
There is a huge difference between bad conductor and insulator, as Bad conductor conducts electricity on a low scale but an insulator does not conduct electricity at all. He mentions that wood, paper, glass, etc. are examples of bad conductor. Wood and paper both can be a bad conductor only in the condition where either one of them is contains water.
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.

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😇
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😃😃😃
Answer- The thick rode of impure copper should be added to the positive terminal as an anode, and the pure copper in the negative terminal as a cathode. This is because, since impure copper has freely moving electrons, it will pass through the electrolyte, and will get deposited on the pure Cu easily. Thank you for the session!
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.

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 .
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.
HW QUESTION KA ANSWER 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.
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.
The thin plate of pure copper mustbe attached to the positive terminal of the battery because during the process of purification the metal deposits of the positive terminal will be there on the cathode so to purify the impur copper,pure copper should be used as positive terminal
A thin plate of pure copper will be attached to the positive terminal of battery because we use plating for only scratches, making things shiny, protect from corrosion so we will plate the thin copper on impure copper rod.
The answer for the homework question: The thin rod of pure copper should be attached to the positive terminal (anode) and the impure copper rood should be attached to the negative terminal (cathode). This is because since current flows from positive to negative terminal, the electroplating will also occur in the same direction.

the thick rod ( impure ) is attached to the positive terminal of the battery.
Because when the electric current is passed through copper sulphate solution, it dissociates ( forms ions) into copper and sulphate.
Free copper is drawn to the negative terminal of the battery and gets deposited on it.
On the other hand, loss of copper from the solution should be 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.

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.
My doubt also same bro
@@shaniasaji9451tq,sir
Nah bro is dumb @@bungasundarsing9954
It uses magnetic effect. It can show deflection still

electroplating is depositing of one mental on other metal... which helps the substance overcome rusting
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
Thin plate at positive terminal because the copper is a positive so it will go towards negative and impurities leftover

Check pg 179 last paragraph. Galvanization is one application of electroplating.
