Question

Chlorine water with potassium iodide in chloroform

Answer 1

Answer:

A test tube contains a layer of potassium iodide solution over a denser layer of carbon tetrachloride. Chlorine is bubbled through the potassium iodide layer. The chlorine reacts with the iodide to form iodine. In the aqueous layer the brown triiodide ion is formed by the reaction of iodine with iodide.
