Answer 6

filter

Question 7

solvent

Answer 7

The part of a solution present in the
largest amount

water part of Kool-Aid

Question 8

Solute

Answer 8

The part of a solution present in a
smaller amount

Kool-Aid powder part of Kool-Aid

Question 9

When is a solution is saturated

Answer 9

when no more solute can be dissolved in the solvent at the present
temperature.

Question 10

what is the relationship between temperature and the solubility of a solid in a liquid

Answer 10

The higher the temperature, the greater the solubility of a solid in a liquid

Question 11

How will adding a solute to a solution affect the solution’s boiling point?

Answer 11

Adding solute to a solution will raise its boiling point

Question 12

. How will adding a solute to a solution affect the solution’s freezing point?

Answer 12

Adding solute to a solution will lower its freezing point

Question 13

how can you increase solubility of a mixture if it is already saturated?

ex: Kim has added several spoonfuls of sugar to her iced tea. Although she has stirred the tea repeatedly, the
sugar will not dissolve. What can Kim do to make the sugar dissolve?

Answer 13

add more solvent
or
heat the mixture
ex: 
Kim can add more water (solvent) to the tea, or heat the tea so that more sugar can dissolve.
