Investigation of the Equilibrium Constant and Thermodynamic Properties of Borax Dissolution Using Titration Techniques
This experiment uses the method of titrating saturated Borax aqueous solution with hydrochloric acid to determine the equilibrium constant of Borax as well as its enthalpy change, entropy change, and standard free energy of dissolution. Using this method, the equilibrium constant was found to be 0.1...

| description | This experiment uses the method of titrating saturated Borax aqueous solution with hydrochloric acid to determine the equilibrium constant of Borax as well as its enthalpy change, entropy change, and standard free energy of dissolution. Using this method, the equilibrium constant was found to be 0.172 for the first Borax sample at 41 ॰C while it was 0.157 for the second Borax sample at 3.9 ॰C. Using a graph of ln(ksp) vs. 1/Temperature, the change in enthalpy was 620,000 J/mol, the change in entropy was -12.72 J/molK, and the standard free energy was 624 kJ/mol. |
