Worksheet Solutions, Suspensions and Colloids

Front

What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (solute) is dissolved in another (solvent).

Front

What is a colloid?

Back

A mixture where tiny particles of one substance are dispersed throughout another substance, but not dissolved. Examples include milk and fog.

Front

What is a suspension?

Back

A heterogeneous mixture in which solid particles are suspended in a liquid or gas and can settle over time. An example is muddy water.

Front

What is the Tyndall effect?

Back

The scattering of light by particles in a colloid, which makes the path of the light visible.

Front

What is an electrolyte?

Back

A substance that dissociates into ions in solution and can conduct electricity. Example: sodium chloride (table salt).

Front

What is the difference between a solution and a colloid?

Back

A solution is a homogeneous mixture where solute is completely dissolved, while a colloid has larger particles that do not settle and scatter light.

Front

What is brass?

Back

An alloy made primarily of copper and zinc, known for its strength and corrosion resistance.

Front

What is the role of water in chemical solutions?

Back

Water often acts as a solvent, dissolving various substances to form solutions.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.

Front

What is a homogeneous mixture?

Back

A mixture that has a uniform composition and appearance throughout, such as saltwater.
