- a Describes two liquids that can be mixed together but separate shortly after you cease mixing them.
- b The lowering of vapor pressure of a solvent by the addition of a nonvolatile solute to the solvent.
- c The process of surrounding solute particles with solvent particles to form a solutions; occurs only where and when the solute and solvent particles come in contact with each other.
- d Contains more dissolved solute than a saturated solution at the same temperature.
- e Hetergeneous mixtures containing particles larger than solution particles but smaller than suspension particles that are categorized according to the phases of their dispersed particles and dispersing mediums.
5 Multiple choice questions
- A physical property of a solution that depends on the number, but not the identity, of the dissolved solute particles.
- The ratio of the number of moles of solute dissolved in one kilogram of solvent.
- The jerky, random, rapid movements of colloid particles that results from collisions of particles of the dispersion medium with the dispersed medium.
- Contains less dissolved solute for a given temperature and pressure than a saturated solution; has further capacity to hold more solute.
- The overall energy change that occurs during the solution formation process.
5 True/False questions
soluble → Describes a substance that cannot be dissolved in a given solvent.
miscible → Describes two liquids that can be mixed together but separate shortly after you cease mixing them.
boiling point elevation → The temperature difference between a solution's boiling point and a pure solvent's boiling point.
suspension → The process of surrounding solute particles with solvent particles to form a solutions; occurs only where and when the solute and solvent particles come in contact with each other.
Henry's law → States that at a given temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid.
