Choose the true statement regarding the reaction given below2Na(g) + Cl2(g)--> 2NaCl(s)
Correct answer: B. Chlorine acts as an oxidizing agent and sodium as a reducing agent
- A. Chloride is oxidized and sodium is reduced
- B. Chlorine acts as an oxidizing agent and sodium as a reducing agent
- C. Chlorine acts as a reducing agent
- D. None of the above
Explanation
In the reaction 2Na(s) + Cl2(g) ⟶ 2NaCl(s), sodium (Na) is oxidized to Na+, losing electrons, and thus acts as the reducing agent. Chlorine (Cl₂) is reduced by gaining electrons to form Cl⁻, acting as the oxidizing agent. Therefore, the correct answer is Option B. Options A and C incorrectly describe the roles of chloride and chlorine, and Option D is incorrect because Option B is the accurate description of the reaction.

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.
