Question

Why solubility of iodine molecule in sulphur dioxide increases on adding alkyl iodide?

Answer 1

Ans➡️ At higher pH, iodine reacts with hydro- xide ions to produce iodide and iodate(I) ions. ... Another way to prevent evaporation of iodine is to add potassium iodide to the iodine solution. In the presence of potas- sium iodide solubility of iodine in water increases due to the formation triiodide ions.
