Solutions Test Review

How do you dilute a solution?

• Add water

• Add solute

• Dump out some of the solution

• Mix 2 solutions together

How can you decrease the concentration of a solution?

• Add more solute.

• Use tweezers to remove the solute.

• Lower the temperature because solubility decreases at low temperatures.

• Pour out half of the solution.

What happens to the solubility of a SOLID when temperature increases?

• Solubility increases

• Solubility decreases

• Solubility is not affected by temperature

• The solid undergoes a chemical reaction

When thinking about solubility of SOLIDS, you can think of...

• whether the solids are combustible

• Bubbles in soda

• Dissolving sugar in coffee

• Mixing oil and water

What happens to solubility of a GAS when temperature increases?

• Solubility increases

• Solubility decreases

• Solubility of a gas is only affected by pressure

• Solubility of a gas never changes

When you think about GASES dissolving in water, you can think of...

• Dissolving sugar in coffee

• Bubbles in soda

• Mixing oil and water

• Boyles' Law: M1V1 = M2V2

How do you know a solution is supersaturated?

• Too much solute was added, so not all of it dissolves. The leftover solute stays solid.

• All solute is dissolved.

• The solute and solvent don't mix, like oil and water.

• The solution increases in size when you freeze it.

If a solution contains the MAXIMUM amount of solute that can be dissolved, we say that the solution is...

• Unsaturated

• Saturated

• Supersaturated

• Aqueous

If a solution contains LESS than the maximum solute that can be dissolved, we say that the solution is...

• unsaturated

• saturated

• supersaturated

• aqueous

If a solution contains MORE than the maximum solute that can be dissolved, we say that the solution is...

• unsaturated

• saturated

• supersaturated

• aqueous
