What is a solution?
A homogeneous mixture of two or more substances.
Identify the solute in a saltwater solution.
Salt.
Identify the solvent in a saltwater solution.
Water.
True or False: A solute can be a solid, liquid, or gas.
True.
What is the process called when a solute dissolves in a solvent?
Dissolution.
Fill in the blank: A __________ is a mixture where particles are dispersed but not dissolved.
Suspension.
What is a colloid?
A mixture in which fine particles are dispersed in a continuous medium.
True or False: Colloids can be separated by filtration.
False.
What is the Tyndall effect?
The scattering of light by colloidal particles.
What type of mixture is milk classified as?
Colloid.
Multiple choice: Which of the following is NOT a characteristic of a solution? A) Homogeneous B) Particles settle out C) Cannot be separated by filtration D) Uniform composition
B) Particles settle out.
What happens to the boiling point of a solvent when a solute is added?
It increases.
Fill in the blank: A __________ is a substance that dissolves a solute.
Solvent.
True or False: Solutions can be either saturated or unsaturated.
True.
What is the main difference between a suspension and a colloid?
Suspensions have larger particles that can settle out, while colloids have smaller, stable particles.
What is an example of a solid in liquid solution?
Sugar in water.

B) Orange juice.
What effect does temperature generally have on the solubility of solids in liquids?
Increases solubility.
Fill in the blank: A __________ is a heterogeneous mixture that appears uniform while being stirred but separates upon standing.
Suspension.
What is the defining characteristic of a homogeneous mixture?
Its composition is uniform throughout.
True or False: Colloids can scatter light.
True.
What is the term for the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature?
Solubility.
Multiple choice: Which of the following is a property of colloids? A) Particles settle out B) Cannot be seen with the naked eye C) Easily separated by filtration D) Uniformly distributed
D) Uniformly distributed.
What is the primary reason why emulsions are considered colloids?
They consist of two immiscible liquids where one is dispersed in the other.
