The paper presented the experimental results of the influence of ozone concentration that supplied the reactor on the pH of distilled water. It is shown that at a constant oxygen consumption pH of the reaction mixture increases with increasing ozone concentration. The rate of pH increase is directly proportional to the ozone concentration when ozone concentration doesn’t exceed 0.3 mmol / l. This means that, its reaction with water in the concentration range from 0 to 0.3 mmol/l has the first order in particular ozone. With increasing ozone concentration in the ozone-oxygen mixture more than 0.3 mmol/l, the reaction order changes to zero and pH of water does not change with increasing ozone concentration that supplied the reactor and depends only on the content of the water-ozone complex in the solution.
