Understanding Mixtures: Solutions, Suspensions, and Colloids

What is a solution in the context of mixtures?

• A mixture where particles are visible and settle over time

• A mixture where a solute is dissolved in a solvent

• A mixture where particles are dispersed but not dissolved

• A mixture where a solute is suspended in a solvent

Which of the following is an example of a solution?

• Instant coffee in hot water

• Sand in water

• Clay in water

• Oil in water

What characterizes a suspension?

• Particles are evenly distributed and dissolved

• Particles are too small to settle or dissolve

• Particles are large enough to settle over time

• Particles are dispersed in a gas

Which of the following is a suspension?

• Sand in water

• Whipped cream

• Nail polish remover

• Milk

What is a colloid?

• A mixture where particles are dispersed but not dissolved

• A mixture where particles are too large to settle

• A mixture where particles are visible and settle over time

• A mixture where particles are dissolved

Which of the following is an example of a colloid?

• Oil in water

• Blood plasma

• Salt in water

• Sand in water

What is an emulsion?

• A type of solution

• A type of colloid where gas is dispersed in a liquid

• A type of colloid where both phases are liquids

• A type of suspension

Which of the following is an example of an emulsion?

• Salad dressing

• Whipped cream

• Smoke

• Sand in water

What is a foam in the context of colloids?

• A colloid where a liquid is dispersed in a solid

• A colloid where a gas is dispersed in a solid

• A colloid where a solid is dispersed in a gas

• A colloid where a gas is dispersed in a liquid

Which of the following is an example of a foam?

• Blood plasma

• Nail polish remover

• Whipped cream

• Sand in water
