Electroplating is the process of coating a thin layer of one metal over another by electrolysis. Electroplating is one of the most common applications of the chemical effects of electric current. It is used in many fields. Iron is used in bridges and automobiles to provide strength. However, iron tends to corrode and rust. Hence, a coating of zinc is electroplated on iron to protect it from corrosion and the formation of rust.

The conducting rods connected to the battery and immersed in the electrolyte are called electrodes. Electrodes carry the current from or to the source. There are two types of electrodes: Anodes and cathodes. The electrode at which the oxidation process occurs, and it is positively charged electrode is known as the anode whereas the electrode at which the reduction process takes place and is negatively charged electrode is known as the cathode.

A liquid or a gel through which an electric current passes is called an electrolyte. For example, a dry cell contains a chemical paste called electrolyte in a cylindrical container made up of zinc.

The positive electrode is called the anode. It is so-called because the negatively charged anions move to the positive anode. Thus, the positive electrode is called the anode.

Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form. The cations are reduced at cathode and anions are oxidized at the anode.

Ions are the atoms or molecules which are electrically charged. The charge can be of two types namely positive and negative.
Thus, there are two types of ions namely cations (positively charged) and anions (negatively charged).

Ornaments are usually made of cheap metal undergo tarnish and corrosion. This reduces the quality of the ornaments, and it cannot be used for longer time. So, they are always coated with expensive metals like gold which does not undergo tarnish with proper care.

A rod, through which an electric current enters or leaves a circuit, having a 'liquid solution' as one of its parts. iss electrode. Electrode is a point where current enters and leaves the electrolyte. Current leaves the negative electrode called as cathode and enters the electrolyte through positive electrode known as anode. Electrodes are the essential components of electrochemical cells
