What is a supersaturated solution?

• A mixture with less solute dissolved in the solvent than is usually soluble.

• A mixture with more solute dissolved in the solvent than is usually soluble.

• A solution that has reached equilibrium with the solute and solvent.

• A solution that contains only the solvent without any solute.

What is the process of dissolving?

• The process of combining two solids into one.

• The process in which solute particles are surrounded by solvent molecules and separated from each other.

• The process of heating a liquid to create vapor.

• The process of mixing two liquids to form a solid.

What is a saturated solution?

• A solution that contains no solute at all.

• A solution in which the maximum amount of solute has been dissolved at a given temperature.

• A solution that can dissolve more solute at a higher temperature.

• A solution that has an equal amount of solute and solvent.

What is concentration in terms of solutions?

• The amount of solute present in a given volume of solvent.

• The total volume of the solution.

• The temperature at which a solution boils.

• The color intensity of the solution.

What is a heterogeneous mixture?

• A mixture that has a uniform composition, such as saltwater.

• A mixture that does not have a uniform composition, such as a salad.

• A mixture that can be easily separated by physical means, such as sand and iron filings.

• A mixture that contains only one type of substance, such as pure water.

What is solubility?

• The ability of a solute to change its state.

• The amount of solute that can dissolve in a certain volume or mass of solvent, at a certain temperature.

• The process of separating a mixture into its components.

• The temperature at which a solvent boils.

What is the difference between a solute and a solvent?

• A solute is the substance being dissolved, while a solvent is the substance doing the dissolving.

• A solute is the liquid in which a substance is dissolved, while a solvent is the solid that dissolves.

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

• A solute is a mixture of two or more substances, while a solvent is a pure substance.

What factors affect solubility?

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

• Only temperature and pressure.

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

• The amount of solute and the time of mixing.

What is a solvent?

• A substance that does the dissolving in a solution.

• A type of chemical reaction.

• A solid that forms in a solution.

• A mixture of two or more liquids.

What is a concentrated solution?

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

• A solution that contains a large amount of solute relative to the amount of solvent.

• A solution that has equal amounts of solute and solvent.

• A solution that is completely saturated with solute.
