Methods of Separating: Homogeneous Mixtures

There are three different types of mixtures based on their components: solid-solid mixtures, liquid-liquid mixtures, and _______ mixtures?

• solid-liquid

• solid-solid

• liquid-liquid

In ________, a solid and liquid solution is heated until it boils. Once the solution boils, the liquid solvent starts to evaporate and leaves behind solid solutes.

• Crystallization

• Distillation

• Evaporation

________ is done by cooling down a solution to lower the solubility of the solute components until crystals are formed.

• Crystallization

• Distillation

• Evaporation

○In order for ________ to work, the components should have a large enough difference in boiling points so that when one component boils, the other remains as a liquid.

• Crystallization

• Distillation

• Evaporation

Answer explanation

Distillation is separation that is based on the differences of the boiling point of the substance in the mixture.

This method is useful in a pharmaceutical industry in determining the amount of each chemical in each product.

• Chromatography

• Distillation

• Evaporation

Answer explanation

Distillation is separation that is based on the differences of the boiling point of the substance in the mixture.

You want to see what colors are all present in a solution. What method would you use?

• Chromatography

• Distillation

• Evaporation

John wants to separate salt from water. What separation technique should he use?

• Chromatography

• Distillation

• Evaporation

To dissolve in water.

• Solubility

• Mixture

• Density

Answer explanation

Solubility refers to the amount of solute that can dissolve in a particular amount of solvent at a specific temperature.

It is the absorbent material that holds the liquid solution still while allowing the mobile phase to travel along.

• Mobile Phase

• Stationary Phase

It is the solvent used to separate the components of the mixture.

• Mobile Phase

• Stationary Phase
