82. which lowers the freezing point of 2.0 kg of water ,ore, 0.20 mol NaOH or 0.20 mol Ba(OH)2? Both compounds are strong electrolytes. Explain?
83. which solution has the higher boiling point, 0.500M glucose or .300M KCL? Explain

82: the Ba(OH)2 lowers the freezing pt more because it will break up into 3 ions (2OHs and 1 Ba) compared to the NaOH which will break up into only 2 ions (Na and OH)
83: the KCl will have a higher boiling pt because it will break up into two ions (K and OH) while the glucose, being a molecular substance will not break up into smaller particles.
10: they will both dissociate to a small extent. The weak acid will produce some H+ protons that will bind with some water molecules and form H3O+ ions. The weak base will produce some NH4+ ammonium ions as it will take an H+ proton from water molecules.
