3 cards from this section. Quick, good the night before a test.
Define Raoult's Law.
Think of it in terms of proportions of each component.
What is meant by an ideal solution?
Recall the definition and characteristics of ideal solutions.
What does Raoult's Law describe?
Remember the context of vapor pressures in solutions.
True or False: Non-ideal solutions follow Raoult's Law.
Think about what happens when components interact.
A solution is made by mixing 50 g of acetic acid (molar mass = 60 g/mol, pure vapor pressure = 0.5 atm) with 150 g of water (molar mass = 18 g/mol, pure vapor pressure = 0.03 atm). Calculate the total vapor pressure of the solution.
Think through the molar relationships and apply the mole fraction into the formula.
Discuss how the addition of a solute affects the vapor pressure of the solvent in an ideal solution. Provide an example.
Consider both solute and solvent contributions in your description.
