What is produced when bromide ions react with chlorine gas?

When bromide ions react with chlorine gas, bromine gas is produced as a result of a redox reaction. In this type of reaction, chlorine acts as a stronger oxidizing agent compared to bromine; thus, it can displace bromide ions from their compounds.

In this process, the chlorine gas gains electrons from the bromide ions, causing the bromide ions (Br-) to lose electrons and oxidize to form bromine gas (Br2). This reaction can be written as:

2Br- + Cl2 → Br2 + 2Cl-

In this equation, chlorine gas (Cl2) is reduced to chloride ions (Cl-), and bromide ions (Br-) are oxidized to form bromine. This illustrates the fundamental principle of displacement reactions where a more reactive species displaces a less reactive one.

The other options do not correspond to the actual products of this reaction. Iodine gas is unrelated to this reaction, as it involves different halogens. Chloride ions are indeed formed, but they are not the primary product of interest here. Potassium chloride is irrelevant in the context of the reaction involving bromide ions and chlorine gas unless potassium ions were specifically involved in a different context. Thus,
