Abstract

Traces of copper (II) ion in 10− 7—10− 5 M (M= mol dm− 3) catalytically accelerated the oxidation reactions of iodide ion to iodine in relatively strong acid solutions (pH≤ 2) in the presence of molecular oxygen under conditions containing relatively high concentrations of I−. When a copper (II) solution was mixed with an iodide solution, after a rapid formation of iodine, it gradually increased according to the reaction times. For about 5 min after mixing, ...
