Question

Explain The Process Of Electro Plating Of Aluminium Over Brass Using Aluminium Nitrate
Al(No3) 2 As

Answer 1

Explanation:

Electroplating is the electrolytic process of deposition of a superior metal on the surface of a base metal or article.

An aqueous solution of sodium argentocyanide is used for the electrolysis of silver as the migration of Ag

+

ions is slow in this solution as compared to AgNO

3

. Hence an even deposition of the silver metal is obtained on the article

Answer 2

Electroplating is a process of plating one metal into another using the principle of electrolysis and migration of cations in an anode and anions in a cathode.

• Electroplating is done mainly to prevent the rusting of metals and to avoid the corrosion of metals.
• In this process of electroplating the metal to be electroplated is kept at the cathode and the anode has to be of inert metals such as graphite or platinum.
• The solution to be used is Aluminium nitrate so when the process starts the Aluminium ions move towards the surface of the material that is to be electroplated and the anion which is nitrate ion moves towards the anode.
