Question

Explain the chemical effect of current with help of diagram. Write the two applications
of this effect. Explain the electroplating method with help of a diagram solve fast​

Answer 1

The resulting effects are called chemical effects of electric current. Example : i) When electric current is passed through the solution of a metal salt, such as solution of copper sulphate, metal gets deposited at the negative electrode, because metal is positively charged.

Answer 2

Answer:

Qn.Explain the electroplating method with help of a diagram?

Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process. In electroplating, the deposited metal becomes part of the existing product with the plating/coating.

Explanation:

In Electroplating, both an anode and a cathode (the metal part to be coated) are immersed in an electrolytic bath that is composed of a solution of salts, including the metal to be plated. A direct current (DC) of electricity is passed through the solution, effecting the transfer of metal ions onto the cathodic surface, plating the metal onto the item.
