Mixtures and Solutions Quiz

What is a mixture?

• A solution with distinct parts

• A combination of two or more substances that are physically combined but not chemically bonded

• A single substance with uniform properties

• A combination of two or more substances that are chemically bonded

Which of the following is an example of a homogeneous mixture?

• Air

• Saltwater

• Trail Mix

• Salad

What is solubility?

• The percentage of solvent by weight

• How much of a particular solute can dissolve in a given amount of solvent at a specific temperature and pressure

• The process of reducing the concentration of a solution by adding more solvent

• The percentage of solute by weight

What is concentration in a solution?

• The percentage of solute by weight

• The process of reducing the concentration of a solution by adding more solute

• How much solvent is present in a solution

• How much solute is present in a solution

What is dilution in a solution?

• The process of separating the solute from the solvent

• The process of mixing two solutions together

• The process of reducing the concentration of a solution by adding more solvent

• The process of increasing the concentration of a solution by adding more solute

When is a solution said to be saturated?

• When it contains as much solvent as it can possibly hold

• When it contains as much solute as it can possibly hold at a specific temperature and pressure

• When it contains equal amounts of solute and solvent

• When it contains more solute than solvent

What is an example of a heterogeneous mixture?

• Sugar dissolved in water

• Trail Mix

• Air

• Saltwater

What is an example of a solution?

• Air

• Trail Mix

• Salad

• Saltwater

What is an example of a practical application of mixtures and solutions?

• Analyzing and treating pollutants in water and air

• Studying the properties of pure substances

• Creating new chemical compounds

• Separating mixtures into their individual components

What is the primary difference between mixtures and chemical compounds?

• Mixtures are always homogeneous, while chemical compounds are always heterogeneous

• Mixtures are always chemically bonded, while chemical compounds are physically combined

• Mixtures retain their individual properties, while chemical compounds do not

• Mixtures are always solutions, while chemical compounds are always mixtures
