Question

Short note on elrctroplating

Answer 1

Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. ... The process used in electroplating is called electrodeposition.

Answer 2

Electroplating: It is a simple method of plating of one metal over another by means of electrolysis. This process is also called as electrodeposition.

Electroplating is very useful application of chemical effect of electric current, through which a lots of processes run in laboratory.

Procedure:In electroplating, first of all two electrodes are connected with a battery and inserted in an electrolytic liquid. In the two electrodes, which metal is to be plated by another is fited as cathode and the second metal is fited as anode. Further the salt solution of  the second metal is placed in the electrolytic medium.

Now when electricity is supplied , the metal ions from salt solution will move towards anode as the ions are positively charged and also when they get connected with cathode, they further get reversed to the anode due to similar charge at the cathode.

In this way, the second metal is plated over the first one. In this process only those metals can be plated which are comparatively less active in electrochemical series.

This process is very useful in modern chemistry.



Use: It is used in anti reacting coating to protect metals from reactions, anti corrosive plating to stop corrosion, heat resistant coating  etc. In all these the most common example is Gold plating.

hope so this will help u buddy.......
