摘要：

In this paper, the concentration functions of electrical conductivity and pH are determined for aqueous solutions of an ionic liquid based on diethanolamine and boric acid (DEAB). Correlations between the physicochemical properties of an aqueous solution of DEAB and the processes of dissociation of the system components were established. Charge carriers in DEAB solutions are shown to be anions. It was established that an aqueous solution of DEAB has unipolar electrical conductivity and anion-exchange properties with an anion transfer number of 0.79.
