Dilution of Solutions Quiz

What is the primary purpose of diluting a solution?

• To decrease the volume

• To increase the concentration

• To change the solute

• To increase the volume and decrease the concentration

What is a stock solution?

• A solution with no solute

• A highly concentrated solution used to prepare diluted solutions

• A solution with a fixed volume

• A solution with a fixed concentration

Which equation is used to calculate the concentration of a diluted solution?

• D1V1 = D2V2

• C1V1 = C2V2

• M1V1 = M2V2

• P1V1 = P2V2

In the dilution equation, what does M1 represent?

• The volume of the diluted solution

• The molarity of the diluted solution

• The molarity of the concentrated solution

• The volume of the concentrated solution

Why does the dilution equation work?

• Because the amount of solute remains constant

• Because the amount of solute changes

• Because the volume remains constant

• Because the amount of solvent changes

What happens to the moles of solute during dilution?

• They are removed

• They remain the same

• They decrease

• They increase

In the example problem, what is the initial volume of the concentrated HCl solution?

• 0.5 liters

• 2.0 liters

• 3.0 liters

• 1.0 liters

What is the final volume of the diluted HCl solution in the example?

• 2.0 liters

• 3.0 liters

• 0.5 liters

• 1.0 liters

What is the molarity of the diluted HCl solution in the example?

• 3.0 M

• 1.5 M

• 12.0 M

• 6.0 M

How do you solve for the final volume (V2) in the dilution equation?

• Add M1 and V1

• Multiply M2 by V2 and divide by M1

• Multiply M1 by V1 and divide by M2

• Subtract M2 from V1
