Question

The chemical reaction due to passage of electric current depends on:

• A. electrodes.
• B. magnitude of current.
• C. density of liquid.
• D. all of the above.

Answer 1

Answer: (A)

electrodes.

The chemical reaction due to passage of electric current depends on electrodes.
For example, electrolysis of aqueous copper sulphate solution using platinum electrodes will give oxygen gas at anode.
On the other hand, electrolysis of aqueous copper sulphate solution using copper electrodes will oxidize Cu to Cu(II) ions at anode.

Chemical reaction does not depend on magnitude of current and density of liquid .
