Colligative properties of solutions depend on the concentration of the solvent n

Question

Colligative properties of solutions depend on the concentration of the solvent number of solute particles in solution chemical nature of the solute polarity of the solute particles Which one of the following gases would be the least soluble in water? nitrogen dioxide, NO2 methane. CH_4 sulfur dioxide. SO_2 hydrogen chloride, HCI Consider a solution made from a nonvolatile solute and a volatile solvent. Which statement is false? the vapor pressure of the solution is always greater than the vapor pressure of the pure solvent. The boiling point of the solution is always greater than the boiling point of the pure solvent. The freezing point of the solution is always less than the freezing point of the pure solvent. The osmotic pressure of a solution varies directly with the molar concentration of the solution. Adding solute to a solution increases each of the following except molality vapor pressure boiling point osmotic pressure Which liquid will have the highest boiling point? aqueous 0.60 m glucose pure H_2O aqueous 0.60 m NaCI aqueous 0.60 m sucrose During osmosis pure solvent diffuses through a membrane but solutes do not pure solutes diffuse through a membrane but solvent does not pure solvent and a solution both diffuse at the same time through a membrane gases diffuse through a membrane into a solution and build up pressure
