Karten in diesem Stapel (35)
- 1surface tensionthe force that acts on the surface of a liquid and that tends to minimize the area of the surface
- 2capillary actionthe attraction of the surface of a liquid to the surface of a solid, which causes the liquid to rise or fall
- 3evaporationthe change of state from a liquid to a gas
- 4nonpolarequal sharing of the bond electrons
- 5solubilitythe ability of one substance to dissolve in another at a given temperature and pressure; expressed in terms of the amount of solute that will dissolve in a given amount of solvent to produce a saturated solution
- 6solublecapable of dissolving in a particular solvent
- 7solutiona homogeneous mixture throughout which two or more substances are uniformly dispersed
- 8solutein a solution, the substance that dissolves in the solvent
- 9solventin a solution, the substance in which the solute dissolves
- 10solvateddescribes a solute molecule that is surrounded by solvent molecules
- 11dipolea molecule or a part of a molecule that contains both positively and negatively charged regions
- 12hydrogen bondthe intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule
- 13universal solventa substance that dissolves most things
- 14aqueous solutiona solution in which water is the solvent
- 15tyndall effectis light scattering by particles in a colloid or else particles in a very fine suspension
- 16electrolytea substance that dissolves in water to give a solution that conducts an electric current
- 17nonelectrolytea liquid or solid substance or mixture that does not allow an electric current
- 18saturated solutiona solution that cannot dissolve any more solute under the given conditions
- 19unsaturated solutiona solution that contains less solute than a saturated solution does and that is able to dissolve additional solute
- 20supersaturated solutiona solution that holds more dissolved solute than is required to reach equilibrium at a given temperature
- 21hydrationthe strong affinity of water molecules for particles of dissolved or suspended substances that causes electrolytic dissociation
- 22immiscibledescribes two or more liquids that do not mix with each other
- 23miscribledescribes two or more liquids that can dissolve into each other in various proportions
- 24Henry's lawthe law that states that at constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas on the surface of the liquid
- 25effervesencea bubbling of a liquid caused by the rapid escape of a gas rather than by boiling
- 26concentrationthe change of state from a gas to a liquid
- 27condensationthe change of state from a gas to a liquid
- 28polardescribes a molecule in which the positive and negative charges are separated
- 29colloidsa mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and that are suspended in a liquid, solid, or gas
- 30precipitatea solid that is produced as a result of a chemical reaction in solution
- 31emulsionany mixture of two or more immiscible liquids in which one liquid is dispersed in the other
- 32suspensiona mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas
- 33vaporizationan element or compound is a phase transition from the liquid phase to vapor
- 34molaritya concentration unit of a solution expressed as moles of solute dissolved per liter of solution
- 35molalitythe concentration of a solution expressed in moles of solute per kilogram of solvent
