Solutions and Colligative Properties

Flashcards based on lecture notes about Solutions and Colligative Properties.

Hydration

The process by which dissolved ions in solution are surrounded by water molecules.

Increased Pressure

Causes an increase in the solubility of gasses in solution.

Rate of Dissolving

The time it takes for a solute to completely dissolve in a solution.

Polar

Solutes that must be dissolved by polar solvents.

Saturated

A solution that contains the maximum amount of solute for a given temperature and pressure.

Dissociating

The process by which an ionic compound dissolves and forms ions in solution.

Solution

A homogeneous mixture that appears uniform.

Solubility

The measure of the maximum amount of solute that 100 grams of water can hold at a given temperature and pressure.

Supersaturated

A solution that contains more than the maximum amount of solute for a given temperature and pressure.

Osmosis

The movement of water across a semipermeable membrane.

Suspension

Contains particles that will settle out over time.

Equilibrium

A state of a system in which for every particle of undissolved solute that goes into solution one dissolved solute particle returns to being an undissolved solute particle.

Tyndall Effect

The ability to scatter light as it passes through a colloid or suspension.

Unsaturated

A solution that contains less than the maximum amount of solute possible for a given temperature and pressure.

Nonpolar

Solutes that must generally be dissolved by nonpolar solvents.
