Agitation

the act of tirring, shaking, or mixing

Aqueous

a solution that has a substance dissolved in water

Colloid

a heterogeneous mixture containing particles that are between 1 nm and 100 nm in diameter

Concentrated

solutions containing a high concentration of solute

Dilute

a solution containing a low concentration of solute

Homogeneous

a mixture having unvaried amounts when sampled; separate physically

Ionization

the splitting of ionic compound into their components when dissolved in water

Molarity

the measure in moles per liter of a solution

Saturated

a solution where the max amount of solute has been reached. Equilibrium

Solubility

the ability of a given substance, the solute, to dissolve in a solvent

Solubility curve

a graph showing the dependence of solubility on temperature

Solute

the substance being dissolved

Solution

a homogeneous mixture formed when dissolving a solute in a solvent

Solvation

the act of dissolving

Solvent

the dissolving medium

Supersaturated

a solution where the max amount has been surpassed and crytals begin to form

Surface tension

the inward force or pull that tends to minimize the surface area of a liquid

Surfactant

the wetting agent such as soap or detergent that decreases the surface tension

Suspension

mixtures from which particles settle out upon standing and the average particle size is greater than 100 nm in diameter

Tyndall effect

the phenomenon observed when a beam of light passed through a colloid or suspension

Unsaturated

a solution where the concentration is low and is capable of dissolving more solute
