solutions and their concentrations

What is a solute?

• The substance that is dissolved into the solution.

• A liquid that dissolves a solute.

• A mixture of two or more substances.

• A solid that cannot dissolve in any liquid.

What is the role of temperature in solubility?

• Increasing temperature decreases the solubility of solids in liquids.

• Temperature has no effect on the solubility of solids in liquids.

• Generally, increasing temperature increases the solubility of solids in liquids.

• Increasing temperature decreases the solubility of gases in liquids.

How can you make a solution more concentrated?

• By adding more solvent.

• By adding more solute.

• By diluting the solution.

• By increasing the temperature of the solution.

What is the difference between a solute and a solvent?

• A solute is the substance that is dissolved, while a solvent is the substance that dissolves the solute.

• A solute is always a liquid, while a solvent is always a solid.

• A solute is the substance that dissolves, while a solvent is the substance that is dissolved.

• A solute and a solvent are the same thing, just different names for the same substance.

What is a saturated solution?

• A solution that has reached its maximum concentration of solute and cannot dissolve any more.

• A solution that contains no solute at all.

• A solution that can dissolve more solute than it currently has.

• A solution that has a lower concentration of solute than the solvent.

What factors can affect the solubility of a substance?

• Temperature, pressure, and the nature of the solute and solvent.

• Only temperature and pressure are important.

• The color of the solute and the size of the solvent molecules.

• The shape of the container and the time of mixing.

What is an unsaturated solution?

• A solution that can hold more solute.

• A solution that contains the maximum amount of solute.

• A solution that has no solute dissolved in it.

• A solution that can hold less solute than it currently has.

What does it mean for a substance to be soluble?

• It means that the substance can dissolve in a solvent.

• It means that the substance can be solid at room temperature.

• It means that the substance can evaporate easily.

• It means that the substance can conduct electricity.

What is a homogeneous mixture?

• A mixture in which the components are evenly distributed and cannot be easily distinguished.

• A mixture where the components are visibly separate and can be easily distinguished.

• A mixture that contains only one type of substance.

• A mixture that changes its composition over time.

What is a supersaturated solution?

• A solution that contains less solute than it can theoretically hold at a given temperature.

• A solution that contains exactly the amount of solute it can hold at a given temperature.

• A solution that contains more solute than it can theoretically hold at a given temperature.

• A solution that contains only solvent without any solute.
