colloids

SolutionColloidsSuspensionsDo not separate on standingDo not separate on standingParticles settle outCannot be separated by filtrationCannot be separated by filtrationCan be separated by filtrationDo not scatter lightScatter light (Tyndall effect)May either scatter light or be opaque

Answer 2

Answer:

A solution mix thoroughly together because the particle of a solid are very tiny.

The solute particles re dispersed in the solvent as single molecules or ion.

The diameter of the dispersed particles ranges from 1

to 10

.

Example ; Saltwater, bleach.

Suspension :

Suspension doesn’t mix together entirely, or if they do, the particles may become unmixed and fall to the bottom.

Dispersed particles or solute in suspension are larger than solutes of solution.

The diameter os these particles is of the order 2000

A

˚

or more.

Example- sand stirred ito water, soot in the air.

Colloids:

The colloids solutions are colloids suspension are intermediate between true solutions and suspensions.

The diameter of the dispersed particles in the solvent of colloid solution ranges from 10

Example: milk, butter.
