Mixtures and Solutions

What is a solute?

• A substance that is dissolved in a solution.

• A liquid that dissolves other substances.

• A gas that is mixed with a liquid.

• A solid that cannot dissolve in any liquid.

What is an example of a homogeneous mixture?

• Sand mixed with salt.

• Oil and water.

• Sugar dissolved in water.

• Fruit salad.

What distinguishes a solution from other types of mixtures?

• A solution has components that are chemically bonded and can be separated by filtration.

• A solution has components that are not chemically bonded but are mixed at the molecular level, and it cannot be separated by filtration.

• A solution contains only one type of molecule and is always a solid.

• A solution is a mixture where the components are visible and can be easily separated.

What is an example of a solution?

• Saltwater, where salt is the solute and water is the solvent.

• Sand and water mixed together.

• Oil and vinegar salad dressing.

• Sugar and flour mixture.

What is a solvent?

• A substance that is dissolved in a solution.

• A substance that increases the temperature of a solution.

• A substance in which the solute is dissolved, usually present in a larger amount.

• A solid that forms when two liquids are mixed.

Can a solution be in solid form?

• No, solutions can only be liquid.

• Yes, a solution can be in solid form, such as alloys like brass.

• Only gases can form solutions.

• Solutions can only be in a homogeneous mixture of liquids.

What is filtration?

• A process used to separate solids from liquids or gases using a filter.

• A method for mixing different substances together.

• A technique for heating liquids to evaporate them.

• A way to compress gases into liquids.

What is the difference between a solution and a suspension?

• A solution is a homogeneous mixture where the solute is completely dissolved, while a suspension is a heterogeneous mixture where particles are not fully dissolved and can settle.

• A solution is a heterogeneous mixture with visible particles, while a suspension is a homogeneous mixture with no visible particles.

• A solution contains larger particles that can settle, while a suspension contains smaller particles that remain evenly distributed.

• A solution is a mixture that can be separated by filtration, while a suspension cannot be separated.

What is the role of temperature in solubility?

• Temperature has no effect on solubility.

• Higher temperatures generally decrease solubility for solids.

• Higher temperatures generally increase solubility for solids.

• Temperature only affects the solubility of gases.

True or False: The solute is present in a larger amount in a solution.

• True, the solute is present in a larger amount.

• False, the solute is present in a smaller amount.

• The solute and solvent are present in equal amounts.

• The solute is always present in a negligible amount.
