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

Which is an example of a solute?

• Egg whites
• Sugar
• Water
• Acetone

Water is a universal solvent

• true
• false
