|
|
When a solute is added to a solvent, the freezing point of the ____ is ____ and the boiling point of the ____ is ______. |
solvent, decreased solvent, increased |
|
|
We use molality, and not molarity, for colligative properties because molarity is ____ dependent. |
temperature |
|

ions molality van't Hoff |
|
|
When NaCl dissolves in water, its van't Hoff factor is ___ |
2 (1 for the Chloride ion and 1 for the Sodium ion) |
|
|
When 1 moles NaCl dissolves in 1 kg water, then the Kbp for water and the molality will be multiplied by ___. |
2 |
|
|
The greater the number of particles in solution, the higher the ____ and the lower the ___ for the solvent. |

|
|
Non-electrolyte solutes (do/do not?) ionize in water and thus their van't Hoff factor is ___. |
do not 1 |
|
|
A good example of a non-electrolyte solute is ____, commonly found in kitchens. |
sugar |
|
|
Barium chloride, has a van't Hoff factor of ___. |
3 (1 Barium ion & 2 chloride ions) |
|
|
Aluminum sulfate has a van't Hoff factor of ___. |
5 (2 for Aluminum ions & 3 for sulfate ions) |
|
|
Glucose (C6H12O6) has a van't Hoff factor of ___. |
1 |
|
|
0.1 m CaCl2 produces ___m chloride ions and ___m Calcium ions for a total of ___m ions. |
0.2, 0.1, 0.3 |
|
|
When grams of a known compound are added to grams of a solvent, then you must know the ____ of the resulting solution so you can get the solution's volume. This will let you determine the ____ of the new solution. |
density (g/mL) molarity |
|
|
Density is not needed to calculate the ____ of a solution, since you need kg solvent, not L solution. |
molality |
