|
Aqueous Solution
|
Water that containsdissolved substances
|
|
|
Brownian motion
|
Thechaotic movement of colloidal particles, caused by collision with particles of the solvent in which they are dispersed
|
|
|
Colloid
|
A mixture whose particles are intermediate in size between those of a suspension and a solute solution
|
|
|
Electrolyte
|
A compound that conducts an electric current when it is in an aqueoussolution or in the molten state; all ionic compounds are electrolytes, but most covalent compounds are not
|
|
|
Emulsion
|
The colloidal dispersion of one liquid in another
|
|
|
Hydrate
|
A compound that has a specific number of water molecules bound to each formula unit
|
|
|
Nonelectrolyte
|
A compound that does not conduct an electric current in aqueous solution or in the
molten state |
|
|
Solute
|
Dissolved particles in a solution
|
|
|
Solvation
|
A process that occurs when an ionic solute dissolves; in solution, solvent molecules surround the positive and negative ions
|
|
|
Solvent
|
The dissolving medium in a solution
|
|
|
Strong Electrolyte
|
A solution in which a large portion of the solute exists as ions
|
|
|
Surfactant
|
Any substances that interferes with the hydrogen bonding between water molecules and thereby reduces surface tension; soaps and detergent are surfactants.
|
|
|
Suspension
|
A mixture from which some of the particles settle out slowly upon standing
|
|
|
Surface Tension
|
An inward force that tends to minimize the surface area of a liquid; it causes the surface to behave as if it were a thin skin
|
|
|
Tyndall Effect
|
Scattering of light by particlesin a colloid or suspension, which causes a beam of light to become visible
|
|
|
Weak Electrolyte
|
A solution that conducts electricity poorly because only a fraction of the solute exists as ions
