Dilution

What is the definition of concentration?

• The process of thinking deeply about something

• Measure of the amount of a substance in a given volume of a solution.

• The state of being mentally absorbed in something

• The act of focusing one's attention on a particular task

What is the definition of dilution?

• The process of converting a solute into a solvent by adding more solution.

• The process of reducing the concentration of a solute in a solution by adding more solvent.

• The process of increasing the concentration of a solute in a solution by adding more solvent.

• The process of separating a solute from a solution by adding more solvent.

Name one factor that affects dilution.

• Concentration

• Pressure

• Temperature

• Volume

What happens to the concentration of a solution when it is diluted?

• The concentration of the solution fluctuates.

• The concentration of the solution remains the same.

• The concentration of the solution increases.

• The concentration of the solution decreases.

What happens to the concentration of a solution when more solute is added?

• The concentration of the solution becomes diluted.

• The concentration of the solution increases.

• The concentration of the solution remains the same.

• The concentration of the solution decreases.

Name one factor that affects the rate of dissolution.

• Temperature

• Pressure

• Particle size

• Stirring rate

When you make a dilution, which of these values remains constant?

• The molarity (M)

• The total moles of solute

• The volume (V)

• The concentration

How many moles of solute are present in 50.0 mL of 0.20M KNO₃?

• 10.0 moles solute

• 0.05 moles solute

• 1.00 moles solute

• 0.01 moles solute

As we dilute a solution.....

• The volume increases and the molarity (M) increases

• The volume increases and the molarity (M) decreases

• The volume decreases and the molarity (M) increases

• The volume decreases and the molarity (M) decreases

A solution that has water as the solvent is called a(n).....

• Aqueous Solution

• Water-Based Solution

• Organic Solution

• Dilute Solution
