Question

:copper sulphate solution is electrolyzed using

Platinum electrodes

1. Which is the oxidizing electrode and reducing electrode.

2. Write the electrolytic reaction which take place at electrodes.

3. What is the colour of electrolyte at the end of electrolysis.

4. State the appropriate observation for the above electrolysis reaction​

Answer 1

Answer:

In the aqueous solution, copper sulphate dissociates into its respective ions. On passing electric current, the copper ions (cations) move towards the cathode and get deposited as copper. Simultaneously, the sulphate ions (anions) move towards the anode. So, blue colour of the solution disappears.
