2 cards from this section. Quick, good the night before a test.
Define boiling point elevation.
Think about what happens to the temperature of water when you add salt.
What does K_b stand for?
Remember, it's specific to the solvent being used.
What is the effect of adding a solute to the boiling point of a solvent?
Recall the definition of boiling point elevation.
True or False: Boiling point elevation is dependent on the identity of the solute.
Consider colligative properties.
Calculate the boiling point elevation of a solution that contains 1.5 moles of solute in 0.5 kg of solvent, given K_b = 0.51 °C kg/mol.
Make sure to compute molality before using it in the elevation formula.
Discuss how the boiling point of seawater differs from that of pure water regarding colligative properties.
Think about the effect of solute concentrations in natural solutions.
