Solutions, Suspensions and Colloids

Front

What is a solution?

Back

A homogeneous mixture where the solute is completely dissolved in the solvent.

Front

What is a suspension?

Back

A heterogeneous mixture where solid particles are suspended in a liquid but can settle over time.

Front

What is a colloid?

Back

A mixture where small particles are dispersed throughout a liquid or gas and do not settle out.

Front

What is the main characteristic of a homogeneous mixture?

Back

All components are evenly distributed and cannot be easily distinguished.

Front

What is the main characteristic of a heterogeneous mixture?

Back

Components are not evenly distributed and can often be seen separately.

Front

Which type of mixture scatters light?

Back

Colloids scatter light due to the small particles they contain.

Front

What happens to the particles in a suspension over time?

Back

The solid particles in a suspension will eventually settle to the bottom.
