Applications of Electroplating:-
1) Chromium is a shiny metal which doesn't corrode and it resist scratches. It is deposited on other chep metals such as iron to make car parts, taps, bicycle handles, wheel rims etc. This makes them look more attractive and also resists corrosion.
2) Gold/silver is electroplated on jewellery made out of a cheaper metal to make it look attractive.
3) Food kept in iron cand gets spoilt because of rusting of iron. To prevent this, Iron is electroplated with tim, which is less reactive than iron.
4) Zinc is electroplated on iron to prevent it from rusting. This process is called galvanization. Nowadays, galvanized pipes are available in markets for using them in areas where water usage is more.
Thanks a lot for this video sir! ❤

correct! :)
Awesome teaching skills
Ans-Application of electroplating are
1. used in jewelry.
2. purification of metal
3. used in medical equipment etc...😀

electroplating the process of deposit metal on another material by means of electricity is called electroplating
Thanks bro it helped thankyou🎉
Exam Is near 😢😢
Nothing is Clear 😨😨
But Don't fear 🤔🤔

We can add salt in distilled water because salt is a good conductor but only when the salt is in liquid form.hence we can add salt in distilled water to get electric charges.

Burner,ornaments.the process of deposit metal on another material by means of electricity is called electroplating.We can add salt in distilled water because salt is a good conductor but only when the salt is in liquid form.hence we can add salt in distilled water to get electric charges.
Application of electroplating are :-
• Chromium plating is done on different parts of cars ,buses and motor cycle to give them shiny appearance.
•Thin layar of gold is plated on silver ornaments and these are called gold plated ornaments.
•Iron used for constructing building are coated with a layer of zinc. This protect iron from corrosion and rusting.
😮
*layer
5:20 the electricity is not being conducted because the water is distilled and there is no salt present in the water
If salt is present in the water than the electricity will be conducted
16:32 Application of Electroplating:
(1) Chromium coating was used for Kicten appliances, bath wear, and car parts.
(2) Medical equipment is made up of nickel which is harmful to us and we use the coating of platinum or gold.
(3) Jellery makers use any other material and then put a coating of gold and silver to give a shiny appearance.
if you add salt then pure water (distilled water) will be the good conductor 🙂
2023 attandance!!
To make the water conducting, we should add salt in it
Electroplating used in Aesthetics
Valuable metals that are rare and expensive as gold and silver are very common examples of this application. With the help of electroplating, a thin layer of these valuable metals can be coated on a cheaper metal which can give an attractive look to the final product at a lower cost.
Many kitchen equipment ,bath taps have a coating of chromiom to prevent from corrosion
2. Medical eqipments are made up of nickel but nickel is harmful to human body so a coating of platinum or gold is done
3 it is a process in which a coating of zinc is applied on iron to prevent it from rusting this process. Is called galvanisation
Easy way
😺 Ions (cat-ions) = 🐾 sitive (paw-sitive) hence, cations are positive 😂😂
Used in jewellery.
Purification of metals.
Changing the texture of metal surfaces.
Preventing corrosion.
Facilitating conduction in circuit boards.
Diatilled Water can conduct if we add any aside or basis like lemon juice and salt solution
Distilled water or pure water does not conduct electricity because no Salt and impurities are present in it.
Bruh that's a straight up legend right there . 💀
He completed the hardest science 8th fricking chapter in 17 mins , that's sick 😳😳😳
U r right. 👍🏻
You are right
Yupp 👍👍😊😊
Yes 😣
He is a legend
Tomorrow is my exam
Thank u mannu bhaiya you save alot of time .
Best of luck to all for your exams
Today is my exam...

You can add some amount of ions which will conduct electricity
5:33 5:45 5:46 iron practical macl
It is used to build up thickness on undersized or worn-out parts, or to manufacture metal plates with complex shape, a process called electroforming. It is used to deposit copper and other conductors in forming printed circuit boards, and copper interconnects in integrated circuits.
Distiiled water does not conduct electricity. Sir you mix salt or emon juice the water conduct electricity. ❤
I am watching the day of exam 😎
11:35 distilled water do not conduct electricity
water + salt = electric pass
5:25 sir you have to mix some salt in this water
16:42 applications of electroplating is were use in jewelrys,kitchen items and etc

Salt 🧂🧂🧂🧂
To make water a conductor you must add salt in it
Nice explanation bhaiya😊
0:29😂😂😂😂 free fire
We can add salt or calcium and minerals to make it more conductor
5:25 sir aap salt mix kar sakthe hai
16:30 applications of electroplating is where we use eletroplating materials like in in kitchen equipments , bicycle ,motocycle ,car etc these all are electroplated because electroplationg increases the life of a object
Kon kon chaper revise kar Raha ha comment karo😅

A electroplating process in which we coated a gold through the process of electroplating.
Aaj mere science ki exam hai sir thanks 👍👍👍👍❤❤❤❤

Diamond can passes electricity which means it is conductor
Electroplating are applied in many cases as followed-
1. It is used in the bathroom equipments,taps,kitchen equipments,etc by being coated by chromium to let the equipments last longer.
2. It used in the medical equipments as they are made from nickles which are harmfull for human beings so they are coated with platinum etc.
We can add some salt to make water as a conducter
Aaj bhai ne new headphone liya h😂

We can add salt in distilled water because salt is
a good conductor but only when the salt is in liquid form hence we can add salt in distilled water to get electric charges
Video to chal dekhulgi pur notes pe
Jayada dyan dungi 😂
After all he is telling that "you can score 95+ After studying these notes😅😂😂😂

Lemon juice for conducting it
Or vinegar also
Applications of electroplating:
It is used in wheel rims,hand bars of cycle,artifical ornament,gas burner,bath taps,cold drink tin can etc
Chooo😢😢😢😢😢😢😢😢
5:26 salt😊
please tell what do we call the solution when salt is added to water??
Aqueous solution or salt solution...
hnn isme bhi electricity pass hojayegi isliye ye good conductor h
Legends:-Good byy sir me jaa raha hu nakhali sona banane aur bechne☠️👀💀
You have add salt
Sodium chloride , Nacl or some conducting material
Thanks sir 🌹🌹🥀🙏🙏🙏🤓
Uses in jewelry
Uses in medical equipment
Uses to purification of metals or golds
Salt and lemon can conduct electricity
Yes, vinegar too but alcohol and oil can't conduct
Yes,bc lemon contain acid whereas salt contain minerals

The most familiar uses of electroplating are:
Used in jewellery.
Purification of metals.
Changing the texture of metal surfaces.
Preventing corrosion.
Facilitating conduction in circuit boards.
Three uses of electroplating are- 1-Tin cans used for storing food are made by electroplating tin metal on to iron. 2-it is used in bicycle to resist rust or corrosion. 3-it is used in LPG stoves to resist rust.

Sir when we mix acids ,base and salts in your water so it's becomes a good conductor and it's conduct electricity
Better and shot than magnet brains 😅😅😅😅😅❤❤❤❤
