alloy
mixture of two or more metallic elements
colloid
mixture containing particles that do not settle
dispersed phase
substance with particles that are spread out and suspended in a colloid, analogous to the solute
dispersion medium
substance in which the particles are suspended in a colloid, analogous to the solvent
fractional distillation
separation of two liquids by boiling in stages
Henry's law
law that states that the amount of a gas that dissolves in a certain type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid at a specific temperature, represented by the equation
hydrated
solvated by water molecules
hydration enthalpy
energy released when one mole of solute becomes completely hydrated
hypertonic
at a pressure higher than the osmotic pressure of bodily fluids
hypotonic
at a pressure lower than the osmotic pressure of bodily fluids
ideal solution
solution for which
ion-dipole interaction
electrostatic interaction between ions and polar ends of molecules with permanent dipoles
isotonic
at the same osmotic pressure as bodily fluids
miscible
able to form a homogeneous (evenly distributed) mixture when added together in any proportion
molality (m)
concentration expressed as the number of moles of a solute divided by the mass of solvent in kilograms
molar solubility
molarity of a compound in a saturated solution
molarity (M)
number of moles of a solute dissolved in 1 liter of solution
mole fraction
concentration expressed as the moles of solvent divided by the total number of all moles in solution
osmotic pressure
pressure needed to stop the flow of water through a semipermeable membrane
saturation point
concentration at which no more solute dissolves in a solution for a given temperature and pressure
semipermeable membrane
barrier through which certain types of particles can pass but not others
solute
dissolved material in a solution
solution
homogeneous mixture of two or more substances
solvated
completely surrounded by solvent molecules
solvent
substance that dissolves a material to form a solution
strong electrolyte
ionic compound that dissociates completely into its component ions in solution
supersaturated
condition in which a solution contains more solute than can be dissolved in the solution under normal circumstances
Tyndall effect
phenomenon of light being scattered by a colloid
unsaturated
condition in which more solute can be dissolved into the solution
weak electrolyte
ionic compound that only partially dissociates into its component ions in solution
