Terms Flashcards
concentrated solution
a solution containing a large amount of solute
concentration
a measurement of the amount of a solute that is dissolved in a given quantity of solvent; usually expressed as mol/L
dilute solution
a solution that contains a small amount of solute
electrolyte
a compound that conducts an electric current when it is an aqueous solution or in the molten state; all ionic compounds are electrolytes, but most covalent compounds are not
immiscible
describes liquids that are insoluble in one another; oil and water are immiscible
miscible
describes liquids that dissolve in one another in all proportions
molarity
the concentration of solute in a solution expressed as the number of moles of solute dissolved in 1 liter of solution
nonelectrolyte
a compound that does no conduct am electric current in an aqueous solution or in the molten state
saturated solution
a solution containing the maximum amount of solute for a given amount of solvent at a constant temperature and pressure; an equilibrium exists between undissolved solute and ions in solution
solubility
the amount of a substance that dissolves in a given quantity of solvent at specified conditions of temperature and pressure to produce a saturated solution
solute
dissolved particles in a solution
solvent
the dissolving medium in a solution
supersaturated solution
a solution that contains more solute than it can theoretically hold at a given temperature, excess solute precipitates if a seed crystal is added
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
unsaturated solution
a solution that contains less solute than a saturated solution at a given temperature and pressure
