Mixtures and Solutions Mastery Quiz

What is the purpose of filtration in separating mixtures?

• To dissolve all the components

• To separate solids from liquids

• To change the temperature of the mixture

• To increase the concentration of the solution

Which of the following is a property of solutions?

• They are always gases

• The solute is visibly distinguishable from the solvent

• They are homogeneous mixtures

• They cannot be separated by filtration

What does the concentration of a solution measure?

• The amount of solvent in a given volume of solution

• The temperature of the solution

• The amount of solute in a given volume of solution

• The pressure applied to the solution

What happens to the solubility of most solids in water as the temperature increases?

• It decreases

• It increases

• It remains the same

• It first increases, then decreases

How does pressure affect the solubility of gases in liquids?

• Increasing pressure decreases solubility

• Increasing pressure increases solubility

• Pressure has no effect on solubility

• Decreasing pressure increases solubility

Which method would be best to separate a mixture of sand and water?

• Evaporation

• Filtration

• Distillation

• Chromatography

What is a characteristic feature of a solution?

• The solute can be filtered out

• It has a variable composition

• It is always liquid

• It does not scatter light

What unit is commonly used to express the concentration of a solution?

• Grams per liter (g/L)

• Kelvin (K)

• Pascals (Pa)

• Meters (m)

What is meant by the solubility of a substance?

• The ability to dissolve in any solvent

• The maximum amount of the substance that can dissolve in a specific amount of solvent at a specified temperature

• The rate at which a substance dissolves

• The temperature at which a substance dissolves

Which factor does NOT affect the solubility of a substance?

• The nature of the solute and solvent

• The pressure of the environment

• The color of the solute

• The temperature of the solution
