Strong electrolyte - compound in an aqueous solution that conduct electricity well/many ions/strong acids contain strong electrolytes

Weak electrolyte - poor conductors of electricity/ very few dissolved ions/ no ionic compounds

Colligative properties - depend on concentration of solution
Vapor-Pressure Lowering
Freezing-Point Depression
Boiling-Point Elevation
Osmotic Pressure
Nonvolatile substance- substance with little tendency to become gas
In nonvolatile substances Boiling-Point rises Freezing-Point lowers

    Here's a visual concept (of sorts) about osmotic pressure. It's much better than some of the ones we've seen in class recently.
