Colligative PropertiesOF SOLUTIONS
Colligative Property A property that depends only on the number of particles, and not on their identity
3 Colligative Properties of Solutions
1) Vapor Pressure Lowering (v.p. ↓)
2) Boiling Point Elevation (b.p. ↑)
3) Freezing Point Depression (f.p. ↓)
Vapor Pressure Lowering (v.p. ↓)
Vapor pressure of pure water What happens if you add sugar in water?
Boiling Point Elevation (b.p. ↑) What happens when you put seasoning in boiling water?
Freezing Point Depression (f.p. ↓)
Antifreeze in a car (C2H6O2, ethylene glycol) Salt on icy roads
Why is the freezing point of a solution lower than that of pure solvent? Talk with your neighbor!
