Understanding Mixtures and Solutions

What type of mixture is defined as a combination of two or more substances that can be separated by physical methods?

A solution is a heterogeneous mixture.

Give an example of a colloid.

What is a mechanical mixture?

Which of the following is an example of a suspension?

What is the role of a solvent in a solution?

An emulsion is a heterogeneous mixture of two _____ that separate when left to stand.

Mixtures

A mixture is a combination of two or more substances that retain their individual properties.
Mixtures can be separated by physical methods.
Mixtures can be homogeneous or heterogeneous.

Solutions

A solution is a homogeneous mixture of a solute and a solvent.
The solute dissolves in the solvent.
Solutions are clear and do not separate with standing.

Colloids

Colloids are opaque homogeneous mixtures.
Colloids have very tiny particles suspended in another substance.
The particles are too small to see with the naked eye.
Colloids do not separate with standing.

Mechanical mixtures

A mechanical mixture is a heterogeneous combination of two substances.
The substances are easily identifiable.

Suspensions

Suspensions are heterogeneous mixtures of a solid and a liquid.
Suspensions separate when left standing.
Suspensions can be separated by filtering.

Emulsions

Emulsions are heterogeneous mixtures of two liquids.
Emulsions separate when left to stand.

Solute and Solvent

The solute is the substance that dissolves in a solvent.
The solvent is the substance that dissolves the solute to form a solution.

Explore the fascinating world of mixtures, solutions, colloids, and emulsions. This quiz covers the definitions, characteristics, and differences between homogeneous and heterogeneous mixtures. Test your knowledge on how these mixtures can be classified and separated.
