What is the Ksp for lithium tetraborate if 50.0 mL of a saturated solution of lithium tetraborate requires 9.11 mL HCl to titrate the tetraborate ion?
Use the Born-Haber cycle to calculate the lattice energy of LiCl(s) given the following data: ?H(sublimation) Li = 155.2 kJ/mol; I1 (Li) = 520 kJ/mol; Bond energy (Cl Cl) = 242.8 kJ/mol; EA (Cl) = 348 kJ/mol; ?Hf (LiCl(s)) = -408.8 kJ/mol. A
