Solutions & Solubility Vocabulary
2
agitation ___ is the act of stirring, shaking, or mixing.
3
aqueous ___ means dissolved in water.
4
colloid A ___ is a heterogeneous mixture containing particles that are between 1 nm and 100 nm in diameter; example: paint.
5
concentrated ___ solutions contain a high concentration of solute.
6
dilute ___ solutions contain a low concentration of solute.
7
dissolution ___ is the act or process of resolving or dissolving into parts or elements.
8
electrolytes ___ are compounds that conduct an electric current in solutions; all ionic compounds are this.
9
homogeneous A ____ mixture has unvaried amounts when sampled; separate physically.
10
hydrogen bond A ______ or 'bridges' are the weak attraction between the positive and negative end of a polar molecule, such as the Hydrogen and Oxygen in water.
11
molarity ____ is measure in moles per liter of a solution.
12
ionization ___ is the splitting of ionic compound into their components when dissolved in water.
13
osmosis The tendency of a fluid, usually water, to pass through a semipermeable membrane is called ___ - always moves from high concentration to low concentration.
14
pressure ___ is the exertion of force upon a surface by an object, fluid, etc., in contact with it.
15
saturated In a ___ solution, the max amount has been reached (equilibrium).
16
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.
17
solubility curve A ___ shows the dependence of solubility on temperature; gasses curve down and solids curve up.
18
solute ___ is the substance being dissolved.
19
solution A homogenous mixture formed when dissolving a solute in a solvent is called a ____.
20
solvation ___ is the act of dissolving.
21
solvent ____ is the dissolving medium.
22
supersaturated In a ____ solution, the max amount has been surpassed and crystals begin to form (unstable).
23
surface area For 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.
24
surface tension ___ is the inward force, or pull that tends to minimize the surface area of a liquid.
25
surfactant ___ is the wetting agent such as soap or detergent that decreases the surface tension.
26
suspension ____ are mixtures from which particles settle out upon standing and the average particle size is greater than 100 nm in diameter.
27
temperature ____ describes the amount of motion of particles.
28
Tyndall effect The ___ is the phenomenon observed when a beam of light passes through a colloid or suspension.
29
unsaturated In a ____ solution, concentration is low and is capable of dissolving more solute.
