Respuesta :
Iodine ions are oxidized to form iodine when the chlorine gas is bubbled in the solution of potassium iodide.
Reaction of some chlorine
When chlorine gas is bubbled into a solution of potassium iodide, some amount of the iodide ions are oxidized and changed into iodine which leads to the formation of beautiful violet color of iodine. This colour can be seen as the iodine dissolves in the carbon tetrachloride layer.
Reaction with concentrated chlorine gas
While on the other hand, when the high concentration of chlorine is bubbled into the solution of potassium iodide, the iodine reacts and formed iodine monochloride which is ruby red so we can conclude that iodine ions are oxidized to form iodine when the chlorine gas is bubbled in the solution of potassium iodide.
