Solutes, Solvents, Solutions

What is the effect of pressure on the solubility of gases in liquids?

• Increasing pressure decreases the solubility of gases in liquids.

• Increasing pressure has no effect on the solubility of gases in liquids.

• Increasing pressure increases the solubility of gases in liquids.

• Increasing pressure only affects solids, not gases.

What is the role of temperature in dissolving a solute?

• Increasing the temperature generally increases the solubility of a solute in a solvent.

• Temperature has no effect on the solubility of a solute.

• Lowering the temperature increases the solubility of a solute.

• Temperature only affects the rate of dissolving, not the solubility.

What is a concentrated solution?

• A solution with a small amount of solute relative to the solvent.

• A solution that contains only one type of solute.

• A concentrated solution has a large amount of solute relative to the amount of solvent.

• A solution that is saturated with solute.

In a saltwater solution, what is the solute?

• Sugar

• Salt

• Sand

• Baking soda

What is a solution?

• A solution is a heterogeneous mixture of two or more substances.

• A solution is a homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

• A solution is a type of chemical reaction between two substances.

• A solution is a solid substance that cannot dissolve in any liquid.

What happens when you stir a solute in a solvent?

• Stirring decreases the rate of dissolution of the solute in the solvent.

• Stirring has no effect on the rate of dissolution of the solute in the solvent.

• Stirring increases the rate of dissolution of the solute in the solvent.

• Stirring causes the solute to settle at the bottom of the solvent.

What is the difference between a saturated and an unsaturated solution?

• A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

• A saturated solution can dissolve more solute than an unsaturated solution.

• An unsaturated solution contains the maximum amount of solute that can dissolve at a given temperature, while a saturated solution can dissolve less.

• Both saturated and unsaturated solutions contain the same amount of solute.

What is a dilute solution?

• A solution with a high concentration of solute.

• A solution that contains no solute at all.

• A dilute solution has a small amount of solute relative to the amount of solvent.

• A solution that is completely saturated with solute.
