Chemistry Chapter 7 Vocabulary

solution

homogeneous mixture of two or more substances where the components are present as atoms, molecules or ions

solvent

substance present in a solution in the largest amount

solute

one or more substances present in a solution in amounts less than that of the solvent

dissolving

term used to describe the process of solution formation when one or more solutes are dispersed in a solvent to form a homogeneous mixture

soluble substance

substance that dissolves to a significant extent in a solvent

insoluble substance

substance that does not dissolve to a significant extent in a solvent

immiscible

term used to describe liquids that are insoluble in each other

solubility

max amount of solute that can be dissolved in a specific amount of solvent under specific conditions of temperature and pressure

saturated solution

solution that contains the max amount possible of dissolved solute in a stable situation under the prevailing conditions of temperature and pressure

supersaturated solution

unstable solution that contains an amount of solute greater than the solute solubilit under the prevailing conditions of temperature and pressure

hydrated ion

an ion in solution that is surrounded by water molecules

concentration

relationship between the amount of solute and the specific amount of solution in which it is contained

molarity (M)

solution concentration expressed in terms of the number of moles of solute contained in a liter of solution

percent

solution concentration that expresses the amount of solute in 100 parts of solution

weight/weight percent

concentration that expresses the mass of solute contained in 100 mass units of solution

weight/volume percent

concentration that exresses the grams of solute contained in 100 mL of solution

volume/volume percent

concentration that expresses the volume of soltue contained in 100 volumes of solution

electrolyte

solute that when dissolved in water forms a solution that conducts electricity

nonelectrolyte

solute when dissolved in water forms a solution that does not conduct electricity

colligative property

solution property that depends only on the concentration of solute particles in solution

osmotic pressure

hydrostatic pressure required to prevent the net flow of solvent through a semipermeable membrane into a solution

osmosis

process where solvent flows through a semipermeable membrane into a solution

osmolarity

product of n and M in the equation (pie)=nMRT

colloid

homogeneous mixture of two or more substnaces where the dispersed substances are present as larger particles than are found in solutions

dispersing medium

substance present in a colloidal dispersion in the largest amount

dispersed phase

substance present in a colloidal dispersion in amounts less than the amount of dispersing medium

Tyndall Effect

property of colloids where the path of a beam of light through the colloid is visible beacuse the light is scattered

emulsifying agent (stabalizing agent)

substance that when added to colloids prevents them from coalescing and settling

dislyzing membrane

semipermeable mebrane with pores large enough to allow solvent molecules, other small molecules and hydrated ions to pass through

dialysis

process where solvent molecules, other small molecules and hydrated ions pass from a solution through a membrane
