These are the three colligative properties that we discussed in our notes.
What are freezing point depression, boiling point elevation, and osmotic pressure?
100
This is a mixture with different proportions of its components dispersed throughout.
What is heterogeneous mixture?
100
This word is used as a qualitative description for a solution with a small amount of solute.
What is dilute?
100
This law states, "The higher the pressure of a gas above a liquid, the more soluble the gas is in the liquid."
What is Henry's Law?
100
This rule describes how to know what type of solvent can dissolve a particular solute.
What is "like dissolves like?"
200
This is how dissolved solute particles will cause freezing point to change.
What is decrease?
200
This is a term that describes two liquids that do not mix.
What is immiscible?
200
This unit of concentration represents the number of moles of solute per liter of solution.
What is molarity?
200
This is what happens to the solubility of a gas as temperature increases.
What is decreases?
200
These are three things that you could do to increase the rate of solvation.
What are increase temperature, increase agitation, and increase solute surface area?
300
The greater the change in this, the greater the change in colligative properties will be.
What is number of dissolved particles?
300
This is the term for a colloidal dispersion of a liquid in a liquid.
What is emulsion?
300
This is the molality of a solution containing 4.2 mol NaCl dissolved in 1500.0 g H2O.
What is 2.8 m (molal)?
300
At 25℃, a gas has a solubility in water of 7.3 g/L at with an external pressure of 3.82 atm of pressure. This will be the solubility of the gas in water if the external pressure increases to 6.04 atm.
What is 11.54 g/L?
300
The Tyndall effect can be observed in these heterogeneous mixtures.
What are colloids and suspensions?
400
Of the following substances, this is the one that will produce the largest number of dissolved particles per formula unit:
MgCl2
KNO3
AlF3
What is AlF3?
400
This is an electrolyte solution in which the solute that does not completely dissolve in solution, so only some of the solute exists as ions.
What is a weak electrolyte?
400
This is the volume of a 10.0 M KCl stock solution that you would need to prepare 3.00 L of a 1.8 M solution.
What is 0.54 L? (What is 540 mL?)
400
This is the level of saturation at which the rate of solvation equals the rate of desolvation.
What is saturated?
400
This is the percent by volume of ethanol when 25 mL is added to 250 mL of water.
What is 9.09%?
500
