The results of studies of the physicochemical properties of extraction phosphoric acids containing magnesium in the presence of ammonium nitrate are presented. A decrease in the heat of vaporization in the H 3 PO 4 -H 2 O system was found in the range of acid concentrations of 20-30% and 37-45% P 2 O 5 . At an acid concentration of 20, 35% and 45% P 2 O 5 there is a minimum electrical conductivity, while at a concentration of 30 and 40% P 2 O 5 , the electrical conductivity of solutions reaches a maximum value at temperatures of 25-45%, which is explained by structural changes occurring in the acid during dissociation and dimerization, depending on the concentration. The electrical conductivity of the H 3 PO 4 -H 2 O system decreases with the introduction of magnesium sulfate and ammonium nitrate. The regularity of the thickening of magnesium-containing acid is substantiated.
