Multiple Choice

How does a solution become supersaturated?

dissolve lots of solvent in it.

dissolve a little solute in it.

dissolve more solute than you should be able to.

dissolve a super amount of solvent in it.

Multiple Choice

When a certain amount of solvent cannot hold any more solute it is called a ________ solution.

Diluted

Saturated

Unsaturated

Supersaturated

Multiple Choice

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

supersaturated

Multiple Choice

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.
