For the reaction of sodium bromide with chlorine gas to form sodium chloride and bromine, what are the appropriate half-reactions? (ox = oxidation and re = reduction) A) ox: 2Br^- → Br₂ + 2e^-; re: Cl₂ + 2e^- → 2Cl^- B) ox: Br + 2e^- → Br^2-; re: 2Cl^- → Cl₂ + 2e^- C) ox: Cl₂ + 2e^- → 2Cl^-; re: 2Br^- → Br₂ + 2e^- D) ox: 2Na⁺ + 2e^- → 2Na; re: 2Cl^- → Cl₂ + 2e^- E) ox: Cl + e^- → Cl^-; re: Br → Br^- + e^-

Quizplus · Accepted Answer

The correct half-reactions for the reaction of sodium bromide with chlorine gas to form sodium chloride and bromine involve the oxidation of bromide ions (Br-) to bromine (Br2) with the loss of electrons, and the reduction of chlorine gas (Cl2) to chloride ions (Cl-) with the gain of electrons. Choice A accurately represents these processes using the correct chemical symbols and states of matter.
