Question

Compare the properties of solution suspension and colloids?
(5 marks answer needed)

Answer 1

Answer:

Explanation:

The particles are larger than 10,000 Angstroms which allows them to be filtered. If a suspension is allowed to stand the particles will separate out. A colloid is intermediate between a solution and a suspension. While a suspension will separate out a colloid will not. Colloids can be distinguished from solutions using the Tyndall effect.

Answer 2

Answer:

Solutions

• Do not saperate on standing .

• Cannot be separated by filtration.

• Do not scatter light .

Colloids

• Do not saperate on standing.

• Cannot be separated by filtration.

• Scatter light ( Tyndall Effect).

Suspension

• Particles settle down.

• Can be separated by filtration.

• May either scatter light or be opaque.
