Colligative Properties Properties of solutions that depend on the number of solute particles, not their identity. Boiling Point Temperature at which a liquid's vapor pressure equals the external pressure, causing it to vaporize. Freezing Point Temperature at which a liquid becomes solid, with equilibrium between solid and liquid phases. Vapor Pressure Pressure exerted by a vapor in equilibrium with its liquid at a given temperature. Osmotic Pressure Force driving water movement from low to high solute concentration through a semipermeable membrane. Van't Hoff Factor Number of particles a solute dissociates into in solution, affecting colligative properties. Ionic Compounds Compounds that dissociate into ions in solution, affecting colligative properties significantly. Covalent Compounds Non-electrolyte compounds that do not dissociate into ions in solution. Osmolarity Concentration of solute particles in a solution, considering ionic dissociation. Osmolality Concentration of solute particles per kilogram of solvent, considering ionic dissociation. Molarity Concentration of a solute in a solution expressed as moles per liter. Molality Concentration of a solute in a solution expressed as moles per kilogram of solvent. Equilibrium State where opposing processes occur at equal rates, maintaining a stable system. Non-electrolytes Substances that do not dissociate into ions in solution, typically covalent compounds. Solute Substance dissolved in a solvent to form a solution, affecting colligative properties.
