Question

Bromine is extracted from brine wells. The process involves treating water containing bromine ion with chlorine gas and extracting the Br2 from the solution using an organic solvent. Write a net ionic balanced equation for the reaction of chlorine gas with bromide ion (Br-).



1. 2Cl2 (aq) + 2Br- (aq) => 4Cl- (aq) + Br2(aq)

2. Cl2 (aq) + 2Br- (aq) => 2Cl- (aq) + Br2(aq)

3. Cl2 (aq) + 4Br- (aq) => Cl- (aq) + Br2(aq)

4. 2Cl2 (aq) + 2Br- (aq) => 2Cl- (aq) + 2Br2(aq)

5. 4Cl2 (aq) + 2Br- (aq) => 2Cl- (aq) + 4Br2(aq)

Explanation / Answer

a net ionic balanced equation for the reaction of chlorine gas with bromide ion (Br-) is 2. Cl2 (aq) + 2Br- (aq) => 2Cl- (aq) + Br2(aq)
