[Storage behavior of Collins' solution under various conditions].

Abstract

It is reported on examinations of the precipitation reactions in the Collins solution. The solution which is produced in three and two compartments, respectively, has been given together and stored under three different conditions. During a period of 48 hours the electrolytes sodium and potassium and the pH-value were controlled. Hereby significant differences of these values are shown in the various kinds of compilation as well as between the three- and the two-compartment solution. No or only slight precipitations in the closed system are observed at 20 and 40 degrees C in contrast to the open system.
