The solubilities of 1-hydroxyethane-1,1-diphosphonic acid in five different solvents including ethanol, isopropyl alcohol, n-propyl alcohol, acetone and acetic acid were determined at temperatures ranging from 288.45 to 327.95 K at atmospheric pressure using a gravimetric method. Van t Hoff equation was used to correlate the experimental solubility data. The calculated values of van t Hoff equation were found to be in good agreement with the experimental data. Further, the dissolution enthalpy and entropy of HEDP in the corresponding solvents were predicted.
