1

What is the number of moles of a solute that is dissolved in 1 L of solution?

molarity

2

What are the particles being dissolved?

solute

3

What is a solution that contains less solute then a saturated solution?

unsaturated solution

4

What is the difference between the boiling point of a solution and the boiling point of a pure solution?

boiling point elevation

5

What describes liquids that dissolve in each other?

miscible

6

What is the substance that does the dissolving?

solvent

7

What contains the maximum amount of solute for a given amount of solvent?

saturated solution

8

What is a liquid that contains more solute then a saturated solution?

supersaturated solution

9

What is the solubility of a gas in a liquid that is directly proportional to the pressure?

Henry's law

10

What describes liquids that are insoluble in each other?

immiscible

11

Can the solubility of a solute be increased by cooling the solvent?

NO

12

Does grinding a solute increase the rate at which it can dissolve?

YES

13

When the temperature of a solvent increases does the solubility of a gaseous solute increases?

NO

14

Is a compound that has a specific number of oxygen molecules bound to each formula unit know as a hydrate?

NO

15

What operations make a substance dissolve faster in a solvent?

Agitation
Crushing the substance into a powder
Raising the temperature

16

What will happen to the solubility of the gas in the liquid if the pressure of the gas above a liquid is decreased?

The solubility will decrease

17

Know how to find molarity of a solution

use your notes

18

What are colligative properties of a solution?

Freezing point depression
Boiling point elevation
Vapor pressure lowering

19

What happens to the freezing point of a mixture when antifreeze is added to a car?

It will decrease

20

What will happen (generally) to the solubility of any gas dissolved in the solvent as temperature of the solvent increases?

It will decrease

21

Be able to find how many moles are present in a solution.

Use your notes

22

What can be said about a glass of iced tea with excess sugar at the bottom?

It is supersaturated

23

Why is salt placed on sidewalks and bridges during winter?

Salt lowers the freezing point of ice and water - which allows ice to melt or never form on the surface
