1. If the solubility of a gas is 6.5 g/L at 808 kPa pressure, what is the solubility of the gas when the pressure is 404 kPa? Show your work. 2. Explain on a particle basis how the addition of a solute affects the boiling point, the freezing point, and the vapor pressure of the solvent. 3. Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH–] is 1 x 10–9 mol/L. Is this solution acidic, basic, or neutral? Show your work. 4. What are 2 factors that determine how much solute will dissolve in a given solvent? 5. What are 3 factors that affect how fast a solute will dissolve in a solvent? 6. Calculate the acid dissociation constant of a weak monoprotic acid if a 0.4 M solution of this acid gives a hydrogen-ion concentration of 0.000 1M? Hint: Monoprotic means containing one proton. Show your work. 7. Give 3 properties of acids and 3 properties of bases.
