Solutions and Suspensions

What is a solution?

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

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

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

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

Give an example of a solution.

• Sand

• Saltwater

• Freshwater

• Sugar

How are solutions different from suspensions?

• Solutions and suspensions have the same physical state.

• Solutions contain undissolved particles, while suspensions are completely dissolved.

• Solutions and suspensions have different chemical compositions.

• Solutions are homogeneous mixtures, while suspensions are heterogeneous mixtures.

Explain the process of making a solution.

• Heating the solvent to a high temperature before adding the solute

• Shaking the solution vigorously instead of stirring

• Mixing the solute first and then adding the solvent

• The process of making a solution involves measuring the solvent, adding the solute while stirring, and adjusting the volume if needed.

What is a suspension?

• A suspension is a type of gas mixture.

• A suspension is a pure substance with no particles.

• A suspension is a solution where solid particles dissolve in a liquid.

• A suspension is a heterogeneous mixture in which solid particles do not dissolve in a liquid but are dispersed throughout it.

Provide an example of a suspension.

• Iron filings in water

• Sugar dissolved in water

• Water and sand mixture

• Oil and water mixture

How can you separate a suspension?

• Distillation

• Filtration, decantation, or centrifugation

• Evaporation

• Sublimation

What are the similarities between solutions and suspensions?

• Both are gaseous mixtures

• Both are transparent in appearance

• Both are classified as elements

• Both are homogeneous mixtures with one substance dissolved or dispersed in another.

Discuss the importance of solutions and suspensions in daily life.

• Solutions and suspensions are harmful to human health

• Solutions and suspensions have no practical applications

• Solutions and suspensions are only used in laboratories

• Solutions and suspensions are essential in daily life for mixing substances, delivering medications, and enhancing various products.

Explain the concept of solubility.

• Solubility is the minimum amount of solute that can dissolve in a given amount of solvent.

• Solubility is the maximum amount of solute that can dissolve in a given amount of solvent.

• Solubility is the average amount of solute that can dissolve in a given amount of solvent.

• Solubility is the constant amount of solute that can dissolve in a given amount of solvent.
