WebSep 22, 2024 · In this experiment you will study the dependence of Ksp for borax on temperature. You will then use your Ksp and temperature data to determine the values of ΔHo rxn, ΔSo rxn, and ΔGo rxn for the dissolution reaction described by Equation 11.5. We can equate the thermodynamic expressions: ΔGo rxn = ΔHo rxn − TΔSo rxn.
