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
