Paheli wants to deposit silver on an iron spoon. She took a silver nitrate ( ${AgNO}_{3}$ ) solution in a beaker and set up a simple circuit for electroplating. Which terminal of the battery should the spoon be connected to? What material should the other electrode be made of?

Solution

The battery's negative terminal should have the spoon attached. The second electrode ought to be created from silver.
For the silver to be deposited on an iron spoon, electroplating is necessary.
The iron spoon that has to be electroplated must be connected to the battery's negative terminal.
Since silver is going to be deposited, the electrode attached to the positive terminal needs to be composed of silver.
Silver nitrate is the cure. When an electric current is supplied, silver nitrate disintegrates into silver and nitrate ions, and the silver ions are drawn towards the negative plate and deposited on the iron rod.

Q. Give reasons:
a)The surface of the article to be electroplated should be free from non-metallic impurities.
b) A low current and for a longer time should be used during electroplating.
c) A direct current and not an a.c current should be used during electroplating.
d) The metal anode has to be replaced periodically during electroplating.
e) Silver nitrate is not preferred as an electrolyte during electroplating of an iron spoon with silver.
f) The article to be plated is always placed at the cathode.

In the circuit given as Fig., Boojho observed that copper is deposited on the electrode connected to the negative terminal of the battery. Paheli tried to repeat the same experiment. But she could find only one copper plate. Therefore she took a carbon rod as a negative electrode. Will copper be still deposited on the carbon rod? Explain your answer.
