COMPLETE QUESTIONS AND CORRECT
ANSWERS BUNDLED REVIEW GUIDE
●● solvent
Answer: the component of a solution that is present in the greatest
amount
●● solute
Answer: a component of a solution that is present in the lesser amount
compared to the solvent
●● solubility
Answer: the maximum amount of solute that will dissolve in a given
amount of solvent under a given set of conditions
●● Henry's Law
Answer: the amount of gas that will dissolve in a liquid at a given
temperature is directly proportional to the partial pressure of the gas
above the liquid
●● Saturated solutions
,Answer: a solution that contains the maximum amount of a solute that
can be dissolved under the conditions as which the solution exists
●● supersaturated solutions
Answer: an unstable solution that temporarily contains more dissolved
solute than present in a saturated solution
●● unsaturated solution
Answer: a solution that contains less than the maximum amount of
solute that can be dissolved under the conditions at which the solution
exists
●● concentrated solution
Answer: a solution that contains a large amount of solute relative to the
amount that could dissolve
●● dilute solution
Answer: a solution that contains a small amount of solute relative to the
amount that could dissolve
●● Aqueous solution
Answer: a solution in which water is the solvent
●● non aqueous solution
, Answer: a solution in which a substance other than water is the solvent
●● Factors that affect rate of solution formation
Answer: 1) state of the subdivision of the solute (crushed vs whole)
2) the degree of agitation during solution preparation
3) the temperature of the solution components
●● concentration
Answer: the amount of solute present in a specified amount of solution
●● percent by mass
Answer: the mass of solute in a solution divided by the total mass of
solution multiplied by 100
percent by mass= (mass of solute/mass of solution) x100
must be the same units (g/g)
●● Percent by volume
Answer: the volume of solute in a solution divided by total volume of
solution multiplied by 100
percent by volume = (volume solute/ volume of solution) x 100
