Unsaturated, Saturated, or Supersaturated Solutions

When a solution is saturated:

• No additional material will dissolve in it
• You need to stir it more 
• Two materials have combined to create a clear liquid
• Crystals form 

How can you tell the saturation of a solution?

• Add more solute.

• It will look cloudy.

• Drink it.

• Stir it.

What is a solute?

• The substance that does the dissolving in a solution.
• The substance that is dissolved into the solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

What is a solvent?

• The substance that does the dissolving in a solution.
• The substance that is being dissolved in a solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

A solution with less than the maximum amount of solute completely dissolved.

• Saturated solution

• Unsaturated solution

• Supersaturated solution

A solution with the maximum amount of solute completely dissolved.

• Saturated solution

• Unsaturated solution

• Supersaturated solution

A solution with more than the maximum amount of solute completely dissolved.

• Saturated solution

• Unsaturated solution

• Supersaturated solution

On the solubility curve for a particular solute, the amount needed to saturate 100 g of water would be

• above the line

• on the line

• below the line

• off the charts

You are given a small beaker of solution at room temp. You add a bit of solute to the solution and it dissolves. The solution was:

• saturated

• unsaturated

• concentrated

• warm

When a solution is saturated:

• No additional material will dissolve in it
• You need to stir it more 
• Two materials have combined to create a clear liquid
• Crystals form
