Data Table: Room Temperature Saturated Solution (25 °C) 100 °C Saturated Solution Volume of saturated, filtered Ca(OH)2 solution that was titrated with HCI 5.0 mL 5.0 mL Volume of HCl solution Concentration of HCI solution used in titration required in the titration to reach the equivalence point 19.5 mL 10.6 mL 0.0120 M 0.0120 M Questions/Calculations: 1. Based on the titration data (but without really having to do any calculations yet), is the calcium hydroxide more soluble in the room temperature water or the 100 °C temperature water? Explain your reasoning. 2. Calculate the molar solubility and then the Ksp value for Ca(OH)2 at room temperature and 100 °C using the titration data. 3. Calculate AG for the dissolution of Ca(OH)2 at room temperature and 100 °C. 4. Assuming they are constant with temperature, calculate AH° and AS° for the dissolution of calcium hydroxide in water. 5. Using the standard thermodynamic values in the Appendix, calculate the theoretical values of AH°, AS°, and AG for the reaction of Ca(OH)2 dissolving in water. Discuss the sign of each and what it tells you about this reaction.
