b. The solubility of borax in water increases as temperature increases. More borax is dissolved at higher temperatures indicating that heat is a reactant. 2. Calculate K sp for: the reaction listed in the lab manual. ΔH°= 1404.0 kJ ΔS°= 4.29 J/K ΔG°= ΔH° -T ΔS° & G=-RTln(K) (-R)(T)(ln(K))= ΔH°-T ΔS° 273 K + 65°C= 333 K (8.314)(333)(ln(ksp))= 1404.0 – (333)(4.29) Ln(K sp )= K sp = 15°C=228 K (-8.314)(288)9ln(k sp ))= 1404.0 (288)(4.29) Ln(K sp )= K sp = 3.

4. Calculate the solubility of borax in grams per liter at 60.0 C and at 15.0, using the value of K sp you calculated for each temperatures from Question 2. 5.Some solid borax may have been transferred along with the saturated solutions. How would/could/did that affect your plot?
