Molarity and Solubility Review

What is the molarity equation?

Which is the equation we use for a dilution?

How does volume affect molarity?

• The greater the volume, the higher the molarity

• The lower the volume, the lower the molarity

• The greater the volume, the lower the molarity

• volume does not affect molarity

• 6.0M

• 1.2M

• 0.17M

In a solution of lemonade mix and water, the solvent is...

• the lemonade mix

• the water

• the dissolved mix in the water

The amount of solute that can be dissolved in a certain amount of solvent at a given temperature is...

• solution

• solvent

• molarity

• solubility

T/F: As temperature increases, solubility decreases

• True

• False

If a solution has solute at the bottom of the beaker that will no longer dissolve, the solution is...

• Saturated

• Unsaturated

• Supersaturated

A supersaturated solution holds ___________amount of solute that can theoretically be held at a given temperature

• less than the maximum

• the maximum

• more than the maximum

• the exact

How do you make a supersaturated solution?

• Heat it up, add the maximum amount of solute, then cool it down

• Add as much solute to the solvent that you can

• Heat the solution up and add more solute

• Add more solute than solvent
