It is found that chlorideion oxidation by ozone via electron transfer mechanism does not occur due to its extremely high endoergicity and negligibly low rate. It is concluded that all processes supposedly associated with this reaction, particularly ozone decomposition in sodium chloride solution initiated by Cl• atoms, do not take place either. It is shown that experimental data on the products and kinetic regularities of the interaction of O3 with Cl– contradict the assumption that the electron transfer reaction is its primary stage. In fact, chlorideion oxidation by ozone proceeds via the mechanism of oxygen atom transfer. It is noted that in order to estimate the possibility of using an ozonated physiological saline in medicine, the for mation of chlorideion oxidation products and ozonation byproducts must be taken into account.
