Isotope exchange of iodine in iodide-iodate melts studied by radio paper chromatography
Description
The isotopic exchange reaction of iodine in fused NaI-NaIO3 and KI-KIO3 systems, which does not proceed until the mixture is melted, is found to be almost instantaneous in homogeneous melts. The equilibrium is attained within a period of less than 5 min at a temperature of 5 deg C above the melting temperature of each composition for both systems. No noticable exchange is observed even after heating the samples for 30 min at a temperature of 20 deg C below the corresponding melting point. A single-step bimolecular association-dissociation mechanism is proposed for the exchange. (author) 22 refs.; 2 tabs
