Step-by-step explanation:
Solutions, colloids and suspensions are the three main classifications of a mixture based on sizes of the particles.
- A solution is a homogeneous mixture of solutes and solvents.
- Suspensions are mixtures of small insoluble particles of a solid in a liquid or gas.
- Colloids are homogeneous mixtures of two phases.
Solutions have the following characteristics:
- The size of particles is small
- The particles do not settle on standing.
- The particles pass through ordinary filter papers.
- They are clear and do not have color.
- They do not scatter light
Suspensions have the following properties:
- The particles dispersed are large
- They settle on standing.
- The particles do not pass through ordinary filter papers
- They do not pass through permeable membrane
- They are visible with microscope or naked eyes.
- They are cloudy
- Scatters light.
Colloids have the following properties:
- Their particles are between those in solutions and suspensions.
- Their particles do not settle on standing.
- Their particles pass through ordinary filter paper.
- They do not pass through permeable membranes.
- Scatters light
