Iron key is to be coated with copper here the cathode use is
Answers
For coating copper on iron, cathode will be - copper sheet.
•The above results can be achieved with the help of electroplating.
•Electroplating is defined as "process of depositing a layer of any desired metal on another material by means of electricity."
•Desired material here is copper, and another material is iron.
•Electroplating is also called as electrode position.
•Copper will be cathode.
•Anode will be iron key.
•Electrolyte used will be copper sulfate solution or salt water.
When iron key is to coated with copper then anode is made of Copper and cathode is made up of Iron key .
Explanation:
This coating of iron key with copper takes place with the help of process called electroplating .
Electroplating
It is defined as "coating desired layer of a substance on other by the process of electrolysis" .
- In this article to be coated is made ---Cathode
- Metal to be deposited is made --anode
- Electrolyte taken is ---salt of metal to be deposited .
For example
If we need to deposit layer of copper on iron key :
- Anode --Copper plate
- Cathode --Iron key
- Electrolyte --copper salt like copper sulphate
