Question

In an electrolytic cell, is it a oxidation-reduction reaction? True or False.

Answer 1

\boxed{\text{True}}

Step-by-step explanation:

Consider the electrolysis of molten MgCl₂.

During electrolysis

• Mg²⁺ gains electrons, so it is reduced.
• Cl⁻ loses electrons, so it is oxidized

`\rm Reduction: Mg^(2+) + 2e^(-) \longrightarrow Mg\\Oxidation: 2Cl^(-) \longrightarrow Cl_(2) + 2e^(-)\\Overall: MgCl_(2) \longrightarrow Mg + Cl_(2)\\\\\text{Electrolysis is a }\boxed{\textbf{redox reaction}}`
