Question 1

What is a suspension

Answer 1

A cloudy mixture in which droplets or tiny pieces of another substance are held with in a substance if you leave it out it will seperate

Question 2

What is a colloid

Answer 2

A cloudy mixture but the deoplets or tiny peices are so small that they do not seperate out easily

Question 3

What is chromatography

Answer 3

Test used to find if fluids are pure substances or solutions

Question 4

What type of mixture is a mechanical mixture

Answer 4

Heterogeneous

Question 5

A solutions is a _____ mixture

Answer 5

Homogeneous mixture

Question 6

What is a unsaturated solution

Answer 6

When more solute can dissolve into the solvent at a given temperature

Question 7

What is a saturated solution

Answer 7

When no more solute can dissolve at a given temperature

Question 8

What is solubility

Answer 8

The maximum amount of solute you can add to a fixed volume of solvent at a given temperature

Question 9

What is the saturation point

Answer 9

Occurs when no more solute can be dissolved in a fixed volume of solvent at that temperature

Question 10

What are the factors affecting solubility

Answer 10

•type of solute
•type of solvent
•temperature

Question 11

Describe what happened to solubility when temperature is increased

Answer 11

For solids and liquids when the temperature is increased the solubility increases, while it is the opposite for a gas

Question 12

Describe the particle model of matter

Answer 12

All matter is made of different particles
Particles are always moving
Particles may be attracted or bonded together
Particles have spaces between them

Question 13

Describe the three factors that affect dissolving

Answer 13

Temperature
•makes the particles move fathers they bump into eachother more often and the heat energy is transferred

Size of pieces
•smaller pieces dissolve faster more surface area

Stirring or agitation
•stirring moves particles around and makes the bump into each other
