Mixtures

What is a homogeneous mixture?

• A homogeneous mixture is a mixture that can be separated into its components by physical means.

• A homogeneous mixture is a mixture that has a uniform composition throughout.

• A homogeneous mixture is a mixture that contains only one type of substance.

• A homogeneous mixture is a mixture that has a non-uniform composition throughout.

Give an example of a homogeneous mixture.

• Saltwater

• Oil

• Concrete

• Milk

What is a heterogeneous mixture?

• A mixture that has a uniform composition throughout.

• A mixture that cannot be separated into its components.

• A mixture that consists of visibly different substances or phases.

• A mixture that consists of only one substance or phase.

How can you separate components in a homogeneous mixture?

• By using electromagnetic methods such as magnetism, electrostatics, or radiation.

• By using biological methods such as fermentation, digestion, or decomposition.

• By using physical methods such as distillation, filtration, or evaporation.

• By using chemical methods such as oxidation, reduction, or precipitation.

How can you separate components in a heterogeneous mixture?
