Question

The electrode to which a sodium cation would migrate to:

• A. anode
• B. nickel metal
• C. ammonium hydroxide
• D. cathode
• E. nickel ion
• F. none of the above

Answer 1

The correct option is D cathode

A sodium cation is positively charged and the cathode is negatively charged. From the basics of electrostatics, we know that opposite charges attract each other.

Hence it migrates to the cathode to get neutralized.

Option $D$ is correct.
