Question

What are colloids and suspensions
?

Answer 1

Suspensions and colloids are heterogeneous mixtures. A suspension is identifiable because its particles are large and settle out of the dispersing medium due to the effects of gravity. The dispersed particles of a colloid are intermediate in size between those of a solution and a suspension.

A colloid is a substance in which microscopic particles are dispersed in a medium, but are not dissolved in it. ... A suspension is similar to a colloid except that the dispersed particles tend to be larger and will eventually settle or form sediment. Difference between Colloid and Suspension

Suspension	Colloid
It is a form of homogeneous solution	It is a form of heterogeneous solution
Particle size greater than 1000 nm	Particle size range from 1-1000 nm
Particles settle down well	Particles do not separate
Can be separated by filtration	Cannot be separated by filtration
May scatter light	Shows Tyndall effect (scatters light)
Opaque	Translucent
Easily visible through naked eye	Not visible through naked eye
