The titration of borate in salt brine with hydrochloric acid titration showed that the boron in salt brine existed as a comprehensive statistical form of “tetraborate.” The supersaturation solubility of magnesium borate was observed in the salt water addition dilution test. In the study of acid salt chemistry, the supersaturation limit solubility of magnesium borate in concentrated brine was determined and 7 times higher than the equilibrium solubility. Differential thermal (FT) spectroscopy was used to record the supersaturated aqueous solution of tetraborate and its dilution and acidification The results of FT IR spectroscopy showed that different polyboroxide anions were present in the aqueous boron-containing solution while the interaction between these particles was observed
