Separations of Mixtures

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded. Each substance retains its own properties.

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout. Examples include elements and compounds.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition and appearance throughout. Examples include saltwater and air.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture that has a non-uniform composition and appearance. Examples include salad and oil and water.

Front

What is density?

Back

Density is the mass of a substance divided by its volume. It is a physical property that can be used to separate mixtures.

Front

What is distillation?

Back

Distillation is a separation technique that relies on differences in boiling points to separate components of a mixture.

Front

What is filtration?

Back

Filtration is a separation technique that uses a barrier to separate solid particles from a liquid or gas.

Front

What is evaporation?

Back

Evaporation is the process of turning a liquid into vapor, which can be used to separate a soluble solid from a liquid.

Front

What is centrifugation?

Back

Centrifugation is a separation technique that uses centrifugal force to separate components of a mixture based on density.

Front

What is the boiling point?

Back

The boiling point is the temperature at which a liquid turns into vapor. It is a key property used in distillation.
