Unit 5: Mixtures and Solutions

Front

What are homogeneous mixtures?

Back

Homogeneous mixtures are mixtures that have a uniform composition throughout. The individual components are not distinguishable, such as milk and iced tea.

Front

What are heterogeneous mixtures?

Back

Heterogeneous mixtures are mixtures where the individual components can be seen and are not uniformly distributed, such as a salad or a mixture of sand and pebbles.

Front

What is a concentrated solution?

Back

A concentrated solution is one that contains a large amount of solute compared to the amount of solvent present.

Front

What is a diluted solution?

Back

A diluted solution is one that contains a small amount of solute compared to the amount of solvent present.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where the solute is completely dissolved in the solvent, while a mixture can be either homogeneous or heterogeneous and the components retain their individual properties.

Front

Can mixtures be physically separated?

Back

Yes, mixtures can be physically separated into their individual components, unlike compounds which require chemical reactions to separate.

Front

What is an example of a homogeneous mixture?

Back

An example of a homogeneous mixture is steel, which is a uniform combination of iron and carbon.

Front

What is an example of a heterogeneous mixture?

Back

An example of a heterogeneous mixture is a salad, where the individual ingredients can be seen and separated.

Front

What does it mean for substances in a mixture to keep their own properties?

Back

In a mixture, the individual substances retain their own physical and chemical properties, meaning they do not change when combined.

Front

What is the definition of solute?

Back

A solute is the substance that is dissolved in a solution, such as salt in saltwater.
