#23-29 Colligative Properties

What is the method used for separating a mixture based on size?

• Distillation

• Chromatography

• Filtration

• Sorting or Magnets

What is the method used for separating a mixture based on differences in boiling points?

• Oil Drop Test

• Distillation

• Titration

• Chromatography

What is the method used for separating mixtures based on differences in solubility?

• Chromatography

• Sorting or Magnets

• Distillation

• Cathode Ray Tube

What is true of a heterogeneous mixture?

• Not uniform in composition and you can see the different parts

• Components are uniformly distributed

• The entire mixture looks the same

• Mixed evenly, molecule by molecule, thus too small to see the different parts

What is true of a homogeneous mixture?

• Not uniform in composition

• Suspensions are a type of homogeneous mixture

• Components are uniformly distributed

• The entire thing does not look the same

What can suspensions often be separated by due to their large particle size?

• Distillation

• Filtration

• Titration

• Sorting and Mixing

What is true of a suspension?

• A type of heterogeneous mixture where when precipitates form a mixture of aqueous solutions, it is created with the solid precipitate settling out in an aqueous medium

• A type of homogeneous mixture that are small in particle size so the particles neither settle nor dissolve in the greater medium

What is true of a colloid?

• Can often be separated by filtration

• Have small particle sizes that cannot be separated by filtration

What is the ability of a colloid being able to scatter light called?

• Resonance Effect

• Inductive Effect

• Electronic Effect

• Tyndall Effect

Which of the following are an example of a colloid?

• Rain

• Fog

• Snow

• Sleet
