Explanation:
Electroplating is an object's coating with a thin metal film deposited during electrolysis by an electrolytic solution. Electroplating is often used on items such as knives and forks (silver plate) to produce an attractive and durable finish. It is also used to protect metals susceptible to corrosion.

Electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode.
Electroplating is a process that uses electric current to reduce dissolved metal ions by the use of electrolysis, to obtain the dissolved metal ions at the other electrode, mostly in the form of a uniform coating.
It is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of metals.
There are also specific types of electroplating such as copper plating, silver plating, and gold plating. It allows the manufacturers to make the product with economical materials and then coat the metals to add properties such as rust proofing, improving its appearance and improving its strength.
How does Electroplating work?
The positive electrode should be the metal that you want to coat the object with. The negative electrode will be the object that should receive the deposit of the electroplating metal. The electrolyte should be a solution of the coating metal, as it is a metal nitrate or sulphate. We can examine this better with few examples;
Silver Plating:

Silver Plating
The object that is to be plated is connected to the negative terminal of the power supply. A piece of silver is connected to the positive terminal. The electrolyte is a silver nitrate solution. This process can also be used to purify silver. We can take an impure block at the positive terminal and a strip of pure silver to the negative. The pure silver is deposited via electrolysis at the negative terminal leaving behind the impurities.
Copper Plating:

Copper Plating
The object that is to be plated is connected to the negative terminal of the power supply. A piece of copper is connected to the positive terminal. The electrolyte is copper Sulphate solution.
Like with silver plating, copper deposition can be used to purify copper. In this case, both the electrodes are made from copper. As the impure positive electrode gradually disappears leaving the impurities behind the negative electrode gradually gets coated with pure copper.
