Rate of Dissolution

What is the process called where the solute dissolves in a solvent to form a solution?

• Evaporation

• Dissolution

• Condensation

• Filtration

What is the rate of dissolution?

• The measurement of how quickly a solute dissolves in a solvent.

• The measurement of how much solute is in a solvent.

• The measurement of the temperature of a solvent.

• The measurement of the color change in a solution.

Which of the following factors affects the rate of dissolution?

• Increase surface area

• Decrease surface area

• Reduce temperature

• Avoid stirring

What does agitation mean in the context of dissolution?

• Cooling the solution

• Stirring the solution

• Adding more solute

• Changing the color of the solution

How does increasing temperature affect the rate of dissolution?

• It decreases the rate.

• It has no effect.

• It increases the rate.

• It changes the color.
