CHEM 102 SI Session - Colligative Properties (Marathon)

How does increasing pressure affect the solubility of a solid in a liquid

• it doesn't

• it increases the solubility

• it decreases the solubility

• it makes it fluctuate

How does increasing pressure affect the solubility of a gas in a liquid

• it decreases the solubility

• it increases the solubility

• it doesn't

• it makes it fluctuate

how does increased temperature affect the solubility of a solid in a liquid

• it makes it fluctuate

• it doesn't

• solubility increases

• solubility decreases

how does increasing temperature affect the solubility of most gases in a liquid

• solubility decreases

• it makes it fluctuate

• solubility increases

• it doesn't

henry's law is used for

• boiling point elevation

• solubility and partial pressure of gases

• IMFS

• freezing point depression

colligative properties directly depend on

• cubic packing

• what type of solute is added

• IMF forces

• how much solute is added

All of these are examples of colligative properties except

• vapor pressure

• surface tension

• osmotic pressure

• boiling point

What happens if the solute in a solution is volatile? Select all that apply

• the solute can't evaporate

• the solute can evaporate

• there will be a higher VP than if it were nonvolatile

• there will be a lower VP than if it were nonvolatile

A pure solvent has a higher VP than a solution with a nonvolatile solute dissolved in it.

• true

• false

What is van hoff's factor (i)?

• the number of particles formed in a solution from one formula unit of solute

• equal to 1 in nonelectrolytes

• equal to the number of ions in an electrolyte

• all of these are correct
