Colligative properties
Types of solutions
increasing of boiling point
Decreasing of Freezing Point
boiling point of solution > boiling point of solvent
Hypertonic solution
Depends on the concentration of the solute
Colligative properties
Isotonic solution
They depend directly on the number of solute particles present in the solution
Hypotonic solution
A solute interrupts the ordering level if the water were in the solid state
The higher the concentration of the solute, the higher the boiling elevation will be
Depression or reduction of freezing point
Osmotic pressure
Osmotic Point
FP of the solution is lower than the freezing point of pure water
Vapor pressure lowering
Process called Osmosis
Lower concentration.
Salt (CaCl2) added to the streets when it snows & the mixture with water freezes = rods without snow
A lot of concentration of dissolved particles.
A semipermeable membrane only allows the passage of the molecules of a solvent and prevents the passage of other substances
Equal concentration.
NaCl is used to achieve desired consistency, homemade ice cream
Osmotic Pressure
The amount of pressure to prevent the net flow of solvent from a dilute solution to a more concentrated solution
