The reaction of sodium bromide with chlorine gas is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).
<h3>What is sodium bromide?</h3>
Sodium bromide is an inorganic compound, white, crystalline with high melting point.
The reaction between halogens is redox reaction
Oxidation – 2Br⁻ ? Br₂ + 2e⁻ loss of electron.
Reduction – Cl₂ + 2e⁻ ? 2Cl⁻ gains of electron.
Thus, the correct option is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).
