Application of the conductimetry to the study of the transformation of KCl and Na2SO4 into K2SO4 between 5 and 30 °C

It is known that K2SO4 can be produced by double decomposition reaction between KCl and Na2SO4. The operated process is realized in two steps, through an intermediate product (glasérite: NaK3(SO4)2). However, there is no data concerning the reaction time of each step of the above mentioned process. In this work, electrical conductimetric technique was used in order to determine the considered parameter as a function of temperature.
