Understanding Aqueous Solutions and Dissolution

What is the role of a solute in an aqueous solution?

• It is the substance that dissolves in the solvent.

• It is the liquid that dissolves the solvent.

• It is the gas that evaporates from the solution.

• It is the solid that forms at the bottom of the container.

Which of the following factors does NOT affect the rate of dissolution of a solid solute in an aqueous solution?

• Temperature

• Surface area

• Agitation

• Color of the solute

If you add more solute to a saturated aqueous solution, what will happen?

• The solution will become unsaturated.

• The excess solute will dissolve.

• The excess solute will remain undissolved.

• The solution will evaporate.

How does increasing the temperature generally affect the rate of dissolution of a solid solute in water?

• It decreases the rate of dissolution.

• It has no effect on the rate of dissolution.

• It increases the rate of dissolution.

• It causes the solute to precipitate.
