What happens when chlorine is bubbled through potassium iodide solution?

When chlorine gas is bubbled through potassium iodide solution, a chemical reaction occurs in which chlorine oxidizes iodide ions (I⁻) to form iodine (I₂). This reaction causes the solution to change color, typically turning from colorless to brown due to the formation of iodine. The overall reaction can be represented as: Cl₂ + 2KI → 2KCl + I₂. This demonstrates the oxidative properties of chlorine and its ability to displace iodine from its compounds.
