Chemical Effects of Electric Current Class 8 Science - Electroplating

A process of depositing a layer of any desired metal on another material by means of electricity is called electroplating. It is one of the most common applications of chemical effects of electric current.
When electric current is passed through the copper sulphate solution there is dissociation (Separation of ions) of copper sulphate. Dissociation signifies separation of positively charged copper ion from negatively charged sulphate ion. Being positively charged the copper ions get attracted towards negatively charged copper plate, where the ion receives electrons and get neutralised. During same time electrons get pulled by positive terminal of battery from the copper plate connected to positive terminal, as a result a neutral copper atom get converted to ion. The ion move in the solution. The process continues as long as current flows through the solution making a coat of copper on the plate connected to negative terminal.
Such a process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.

Mam, how can you do coatimg of copper with copper itself 😅 and not understanding anything.... Please do this video again...

[saptasmita_]

You should show with two different metals

[parthbansal]

Mam it clear my doubt... thanks a lot 🙏

[prakrutipratyasha]

Thank you very much ma'am. It was very helpful😊

[arunya]

ma'am positive electrode is connected to the negative terminal as electric current passes from positive terminal to the negative terminal. The position of battery is wrong .

[mdosman]

In electroplating, is there any change in colour of copper sulphate solution or copper plate?

[Alankrita_ghai]

Thankyou mam for the wonderful explanation 😊

[adarshtripathi]

Thank you ma'am
My all doubts are clear .
Thank you so much ma'am .
You are the world's best teacher

LEDs are comprised of compound semiconductor materials, which are made up of elements from group III and group V of the periodic table (these are known as III-V materials). Examples of III-V materials commonly used to make LEDs are gallium arsenide (GaAs) and gallium phosphide (GaP).

Maam ek request.aese saare videos banaate raho. Pls

[krithik]

When the plate which is connected to negative terminal of the battery which is a copper plate then how can copper be deposited in that plate. Plz clarify my doubt

[rakhisharma]

This is the process of electrolysis not electroplating.

[ronakshah]

Couldn't understand a Please use scientific terms like cathode and Disappointed 😟

Legends are watching 8 hours before exam😂

[JayaSree-md]

Very short video not understanding the thing
