Write the use of the chemical effect of electric current?
Hint: There are several uses of the chemical effect of electric current. But the main and great use of the chemical effect of electric current is in the process of electroplating. So, electroplating is the general process of covering the solid substrate with the other metal using the reduction of the cations of the metal.
Complete answer: As said above there are many more uses of the chemical effect of electric current in addition to electroplating. So first let’s discuss some other uses also: In general water is an insulator , but with the help of electric current it acts as a conductor i.e. when the electric current is passed through the water continuously, then it somehow breaks into the weak ions and starts to act as a conductor. Also, the water then provides the surface for the chemical reactions to take place. And also the formation of bubbles is the use. It is also used to change the colour of the solution as well. Now, we come to the most important use i.e. electroplating. Electroplating is the common process in which the solid substrate is coated with another metal by the reduction of the cations of that metal by means of a direct electric current. And the new metal coating acts as the part of the existing product.
Note: This electroplating technique is of considerable use as it protects the metal from the corrosion and maintains the decorum of that metal. There are several types of electroplating techniques like copper plating, silver plating, chromium plating and many more.
