What is the pH value of a neutral solution according to the pH test chart?

• 5.0

• 6.0

• 7.0

• 8.0

According to the pH test chart, which pH value indicates an acidic pH?

• 4.0

• 7.0

• 8.0

• 10.0

What pH value is shown as alkaline on the pH test chart?

• 5.0

• 6.0

What is a solute in a solution?

• The substance doing the dissolving

• The substance being dissolved

• The mixture that has the same composition throughout

• Solutions can also be gaseous like air

What is a solvent in a solution?

• The substance being dissolved

• The mixture that has the same composition throughout

• The substance doing the dissolving

• Solutions can also be gaseous like air

Which of the following best describes a solution?

• A substance being dissolved

• A substance doing the dissolving

• A mixture that has the same color, density, and taste throughout

• A gaseous mixture like air

Which of the following is NOT a way to speed up the rate of the dissolving process?

• Increase temperature

• Decrease surface area

• Stirring

• Increase contact with solvent

How does increasing temperature speed up the dissolving process?

• It decreases the kinetic energy of particles

• It increases the distance between particles

• It increases the kinetic energy of particles, causing them to move apart

• It allows more solvent to come in contact with solute

What effect does stirring have on the dissolving process?

• It decreases the rate of dissolving

• It prevents the solute from dissolving

• It brings more solvent into contact with the solute

• It reduces the temperature of the solvent

What is the result of increasing the surface area of the solute?

• It decreases the rate of dissolving

• It has no effect on the dissolving process

• It increases the rate of dissolving by allowing more solvent to come in contact with the solute

• It increases the temperature of the solvent
