What is the relationship between solubility and temperature according to the solubility rule?
The amount of solute that dissolves in a solvent is dependent on temperature and the saturation limit of the solvent.
What does Raoult's law state regarding the vapor pressure of a solution?
The vapor pressure of a solution is equal to the product of the molality of the solution and the vapor pressure of the pure solvent.
Explain freezing point depression and boiling point elevation in relation to the concentration of a solute in a solvent.
The freezing point of a solvent decreases and the boiling point increases with the addition of a solute, depending on the concentration of the solute.
How is the molality of a solution calculated?
Molality (m) = moles of solute / kg of solvent
Why is the capacity of the polystyrene container used by the professor important in the demonstrations?
The capacity of the container limits the amount of solute that can be added to the solvent, affecting the demonstration outcomes.
Name two pieces of equipment mentioned in the text that the professor uses in his demonstrations.
Burette and thermometer
Study Notes
