Properties of Solution Solution Composition Colligative Property Factors Affecting Solubility Energies of Solution Formation

For Dilute aqueous solutions, Solution Composition Molarity (M) - number of moles of solute per liter solution Molality (m) – number of moles of solute per kilogram of solvent For Dilute aqueous solutions, Molarity = Molality HOME Mass Percentage

Mole, Mass Percentage Mole Percent Mass Percent HOME

Colligative Property Vapor Pressure Boiling Pressure Depression Freezing Pressure Depression Osmosis HOME

Vapor Pressure Vapor Pressures - equilibrium pressure of gas molecules from that liquid above the liquid itself HOME

Boiling Point Depression ΔTbp = Kbp msolute HOME

Freezing Point Depression ΔTfp = Kfp msolute ∴The addition of solute RAISES the boiling point The addition of solute LOWERS the freezing point HOME

Osmosis Osmosis: The movement of solvent molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration. HOME

Factors Affecting Solubility Structure Pressure Temperature HOME

Structure Solubility of a solute in a solvent purely depends on the nature of both solute and solvent Solubility of a non-polar solute in a solvent is large Polar solute has low solubility or insoluble in a non-polar solvent HOME

Pressure HOME

Temperature HOME
