Sodium can be extracted by heating naturally occurring salt until it is molten. An electrochemical process is then used to extract the sodium. Cl2 is produced at the anode, and Na is collected at the cathode.

Question

Write the half-reactions that occur at the anode and the cathode. Identify each as either oxidation or reduction. (4 points)

Answer 1

Nn+ + e- >> Na gains electron, redkuction
3Cl- >> Cl2 + 2e= loses electrons, oxidation
