b.The solubility of borax in water increases as temperature increases. More borax isdissolved at higher temperatures indicating that heat is a reactant.2.Calculate Kspfor: the reaction listed in the lab manual.ΔH°= 1404.0 kJ ΔS°= 4.29 J/KΔG°= 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(Ksp)=Ksp=15°C=228 K(-8.314)(288)9ln(ksp))= 1404.0 (288)(4.29)Ln(Ksp)=Ksp=3.
4.Calculate the solubility of borax in grams per liter at 60.0 C and at 15.0, using the value of Kspyou 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?
