Question 17

Know how to find molarity of a solution

Answer 17

use your notes

Question 18

What are colligative properties of a solution?

Answer 18

Freezing point depression
Boiling point elevation
Vapor pressure lowering

Question 19

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

Answer 19

It will decrease

Question 20

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

Answer 20

It will decrease

Question 21

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

Answer 21

Use your notes

Question 22

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

Answer 22

It is supersaturated

Question 23

Why is salt placed on sidewalks and bridges during winter?

Answer 23

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