Answer 2

Answer:

Explanation:

Given:

A  circuit set up which is used for purification of copper

To find:

a.Name metal used for electrodes A and B

b.Purification process name

c.Solution which is used in the process

Solution:

Electrolysis:

To obtain pure copper we take one electrode which is made up of impure metal and other electrode made up of pure metal.

The  solution which is used in this process is made up of  same metal which is used in electrodes.

This process is called electrolysis.

Therefore,

a.Electrode A-Pure copper
