Electrolysis of a dilute solution of NaCl results at the anode_.
Correct answer: C. Chlorine
- A. Sodium
- B. Hydrogen
- C. Chlorine
- D. Oxygen
Explanation
Chloride ions (Cl⁻) are attracted to the positive electrode (anode) during the electrolysis of a dilute solution of NaCl. At the anode, chloride ions undergo oxidation and release electrons. This leads to the formation of chlorine gas (Cl₂) at the anode.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
