Solutions

Question 1

What is a solution?

Answer 1

A solution is a homogeneous mixture when one material dissolves in another

Question 2

What is a solvent?

Answer 2

A solvent is a substance that dissolves a solute, resulting in a solution

Question 3

What is a solute?

Answer 3

A homogeneous mixture composed of two or more substances.

Question 4

What does dissolve mean?

Answer 4

To be broken up or absorbed by something or to disappear into something else.
Substances that dissolve in water are called soluble substances.

Question 5

What does soluble mean?

Answer 5

Able to be dissolved

Question 6

What does insoluble mean?

Answer 6

Incapable of being dissolved.

Question 7

What is a suspension?

Answer 7

• Formed when an insoluble solid mixes with a liquid, and does not dissolve
• Suspensions are heterogeneous mixtures
○ Particles of the solid are quite large, and visible
○ This makes the suspension opaque (cloudy, not transparent)
○ The particles of solid will settle to the bottom over time
○ Suspensions are separated by filtration

Question 8

What is a colloid?

Answer 8

• Colloids are hybrid solutions and suspensions
• Colloids are heterogenous mixtures, where the particles are evenly distributed, but not dissolved
• The particles are smaller than in suspensions, so do not settle out over time, they stay mixed
• The particles scatter light so colloids are opaque (cloudy)
