Saturated vs Unsaturated POGIL Assessment

__________ are made up of solutes and solvents.

• Solutions
• Suspension
• Compounds

• Mixtures

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

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 

How do you know when you have a saturated solution?

• You don't see anymore material in the solution. It has dissolved.

• The material dissolves and no more will dissolve because you see it collect at the bottom.

• The solution is bubbling and cloudy.

• The solution is clear and there is nothing at the bottom.

What is this image representing?

• Saturated

• Unsaturated

• Supersaturated

• Insoluble

If you were handed a beaker containing a clear solution (with no solid solute at the bottom), what is a simple test you could perform to determine if it is saturated or unsaturated?

• taste it to see if it is sour

• add more solute, if it dissolves then the solution is saturated

• add more solute, if it doesn't dissolve the solution is saturated.

• add more solvent, if solid does not form it is unsaturated

Which of the following statements is true?

• B is a saturated solution

• A is a supersaturated solution

• C is an unsaturated solution

• None of the above
