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.
