Solutions Suspensions & Colloids

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (solute) is dissolved in another (solvent). Example: Sugar dissolved in water.

Front

What is a suspension?

Back

A suspension is a heterogeneous mixture where solid particles are dispersed in a liquid but will settle over time. Example: Oil spill in the ocean.

Front

What is a colloid?

Back

A colloid is a heterogeneous mixture where tiny particles are dispersed throughout a liquid or gas and do not settle out. Example: Milk.

Front

Which type of mixture is clear?

Back

Solutions are clear because the solute is completely dissolved.

Front

What does homogeneous mean?

Back

Homogeneous means that the mixture has a uniform composition throughout.

Front

What does heterogeneous mean?

Back

Heterogeneous means that the mixture has a non-uniform composition, with different components visible.

Front

Can colloids settle?

Back

No, colloids do not settle out over time.
