Solutions, Suspensions, & Colloids

Front

What is a solution?

Back

A homogeneous mixture where one substance (solute) is dissolved in another (solvent), resulting in a single phase.

Front

What is a colloid?

Back

A mixture where small particles are dispersed throughout a continuous medium, but do not settle out, such as paint or milk.

Front

What is a suspension?

Back

A heterogeneous mixture where solid particles are suspended in a liquid or gas and can settle out over time, like flour in water.

Front

What property do acids exhibit regarding electrical conductivity?

Back

Acids exhibit high electrical conductivity due to the presence of ions that can carry electric current.

Front

What is the difference between a solution and a suspension?

Back

A solution is homogeneous and does not settle, while a suspension is heterogeneous and the particles can settle out.

Front

Can colloids be separated by filtration?

Back

No, colloids cannot be separated by ordinary filtration due to the small size of their particles.

Front

What is an example of a colloid?

Back

Examples of colloids include milk, fog, and paint.

Front

What happens to the particles in a suspension over time?

Back

The particles in a suspension will eventually settle to the bottom if left undisturbed.

Front

What is the Tyndall effect?

Back

The Tyndall effect is the scattering of light by colloidal particles, which makes the path of the light beam visible.

Front

What is the role of a solvent in a solution?

Back

The solvent is the substance that dissolves the solute, forming a solution.
