Solutions

Question 1

Describe the process of dissolving

Answer 1

-When you add a solid (the solute) to a liquid (the solvent)
-The bonds holding the solute molecules together sometimes break
-The molecules mix with the molecules in the liquid -> forming a solution

Question 2

Define a solution

Answer 2

A mixture of a solute and a solvent that does not separate out

Question 3

Define a solute

Answer 3

The substance being dissolved

Question 4

Define a solvent

Answer 4

The liquid the solute is dissolving into

Question 5

Define a saturated solution

Answer 5

A solution where the maximum amount of solute has been dissolved, so no more solute will dissolve in the solution

Question 6

Define solubility

Answer 6

A measure of how much solute will dissolve in a solvent

Question 7

What is solubility often measured in?

Answer 7

grams of solute per 100 grams of solvent

Question 8

What is the relationship between solubility of most solid substances & temperature?

Answer 8

As temperature increases, solubility of most solid substances increases

Question 9

What is a graph of solubility versus temperature known as?

Answer 9

Solubility curve

Question 10

What can you use solubility curves to see?

Answer 10

The solubility of a substance at a specific temperature

Question 11

How do you read a solubility curve?

Answer 11

• Draw a line from the temperature that you’re interested in (on the x-axis) up to the curve
• Then, read across from the curve to the y-axis to find the solubility of the substance at that particular temperature
