Solutions & Solubility Vocabulary

agitation___ is the act of stirring, shaking,

or mixing.

aqueous___ means dissolved in water.

colloidA ___ is a heterogeneous mixture

containing particles that are between 1 nm and 100 nm in diameter; example: paint.

concentrated___ solutions contain a high

concentration of solute.

dilute___ solutions contain a low

concentration of solute.

dissolution___ is the act or process of

resolving or dissolving into parts or elements.

electrolytes___ are compounds that conduct

an electric current in solutions; all ionic compounds are this.

homogeneousA ____ mixture has unvaried

amounts when sampled; separate physically.

hydrogen bondA ______ or 'bridges' are the weak

attraction between the positive and negative end of a polar molecule, such as the Hydrogen and Oxygen in water.

molarity____ is measure in moles per liter

of a solution.

ionization___ is the splitting of ionic

compound into their components when dissolved in water.

osmosisThe tendency of a fluid, usually

water, to pass through a semipermeable membrane is called ___ - always moves from high concentration to low concentration.

pressure___ is the exertion of force upon a

surface by an object, fluid, etc., in contact with it.

saturatedIn a ___ solution, the max amount

has been reached (equilibrium).

solubility___ is the characteristic physical

property referring to the ability of a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium.

solubility curveA ___ shows the dependence of

solubility on temperature; gasses curve down and solids curve up.

solute___ is the substance being

dissolved.

solutionA homogenous mixture formed

when dissolving a solute in a solvent is called a ____.

solvation___ is the act of dissolving.

solvent____ is the dissolving medium.

supersaturatedIn a ____ solution, the max

amount has been surpassed and crystals begin to form (unstable).

surface areaFor solids, ___ is the portion on

the outside, that is exposed to the elements, such as wind, water, sun, etc. In solutions, increasing this will increase the rate of dissolution.

surface tension___ is the inward force, or pull

that tends to minimize the surface area of a liquid.

surfactant___ is the wetting agent such as

soap or detergent that decreases the surface tension.

suspension____ are mixtures from which

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

temperature____ describes the amount of

motion of particles.

Tyndall effectThe ___ is the phenomenon

observed when a beam of light passes through a colloid or suspension.

unsaturatedIn a ____ solution, concentration

is low and is capable of dissolving more solute.
