Solutions part 2

Name the 3 types of solutions in chemistry:

(There will be three answers)

• Unsaturated solution

• Geometry solution

• Supersaturated solution

• Saturated solution

Order the following from least amount of solute (1) to most amount of solute (3).

• Unsaturated

• Saturated

• Supersaturated

In a saturated solution, if you add more solute, it will ​ (a)   ​ and settle at the ​ (b)   of the container.

• not dissolve
• bottom
• evaporate
• dissolve
• top

In order to create a supersaturated solution, the ___________ must be elevated and then slowly ______ without allowing the excess solute to crystallize out.

• density, raised

• weight, disturbed

• temperature, cooled

• solid, broken

Match the following definitions:

• More solute can be dissolved

• Saturated solution

• contains more solute than normal

• Supersaturated solution

• Maximum amount of solute dissolved

• Unsaturated solution

The following:

Temperature

Agitation (shaking or stirring)

Particle size

Are all factors that affect __________

Label the x and y axis with the correct units

a

b

Solubility

Temperature

Order the following steps in the correct order:

• Find the line for the substance

• Find the temperature and follow up to the line.

• Read across to the y-axis and this is the answer.

Solubility curves are used to show what?

• Relationship between solubility and pressure
• Relationship between solubility and temperature
• Relationship between solubility and pH
• Relationship between solubility and concentration

Based on KNO₃, (the red line) label the area where the solution is unsaturated, saturated, and supersaturated.

a

b

c

Supersaturated

Saturated

Unsaturated
