3 cards from this section. Quick, good the night before a test.
Define abnormal molar mass.
Think about how solute particles behave in solutions.
Explain what the van't Hoff factor represents.
It's linked to how many solute molecules break into ions or group together.
What happens to the observed molar mass when an ionic compound dissociates in solution?
Think of solute as breaking into smaller pieces.
The van't Hoff factor (i) is used to calculate which property?
It's applied wherever solute behavior matters.
If the normal molar mass of a solute is 180 g/mol and the abnormal molar mass observed in solution is 90 g/mol, calculate the van't Hoff factor.
Use the formula for van't Hoff factor.
Consider a solution exhibiting a positive deviation from Raoult's law. Provide possible reasons for this occurrence, with examples.
Identify essential interactions when mixing.
