The article describes an experimental method for determining the effect of salt water based on NaCl, MgCl2 and KCl salts on the efficiency of solar pond heat collection and their physicochemical properties. To determine the density profile, concentration and heat capacity of these salts in the course of experimental work, separate salt solutions of each salt were prepared in the solar pond device. Based on the study of samples taken from different points of the reservoir, the density profile of each salt was studied and graphs were plotted. With the help of an adiabatic colorimeter made for the experiment, the heat capacity of each salt brine was studied in the temperature range of 20°C-70°C and brine concentrations of 5%-28% and graphs of changes at various temperatures were presented.
