1. Chlorine with Potassium Bromide (KBr):
- When chlorine gas (Cl2) is passed into a solution of potassium bromide (KBr), a displacement reaction takes place.
- In this reaction, the more reactive chlorine atoms replace bromide ions (Br-) to form bromine gas (Br2) and potassium chloride (KCl).
- The balanced chemical equation for this reaction is:
Cl2 + 2KBr → 2KCl + Br2
2. Chlorine with Potassium Iodide (KI):
- When chlorine gas (Cl2) is passed into a solution of potassium iodide (KI), another displacement reaction occurs.
- Similar to the reaction with bromide, chlorine atoms replace iodide ions (I-) to form iodine gas (I2) and potassium chloride (KCl).
- The balanced chemical equation for this reaction is:
Cl2 + 2KI → 2KCl + I2
In both reactions, chlorine gas acts as an oxidizing agent, accepting electrons from bromide and iodide ions to form their respective elemental halogens (bromine and iodine gases).
