Question

Describe the redox reaction. Check all that apply.

2Na(s) + Cl2(g) → 2NaCl(s)

Sodium atoms are oxidized.

Chlorine atoms lose electrons.

Chlorine is the reducing agent.

Sodium transfers electrons to chlorine.

Sodium chloride is the oxidizing agent.

Answer 1

Correct:
- Sodium atoms are oxidized. (Na → Na+ + e−)
- Sodium transfers electrons to chlorine. (electrons flow from Na to Cl)

Incorrect:
- Chlorine atoms lose electrons. (They gain electrons: Cl2 + 2 e− → 2 Cl−)
- Chlorine is the reducing agent. (Cl2 is the oxidizing agent; it is reduced.)
- Sodium chloride is the oxidizing agent. (NaCl is the product; Cl2 is the oxidizing agent.)
