Question

Describe homogeneous, heterogeneous, suspension,colloid.

Answer 1

A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. Example - air.
Conversely, a heterogeneous mixture has components whose proportions vary throughout the sample. Example - sand and water.
Simply, we can understand this as, a homogeneous mixture of material means that when dividing the volume in half, the same amount of material is suspended in both halves of the substance.
Suspension and colloids are heterogeneous mixture based on particle size.
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.
Example of suspension - sand and water
Example of colloid - milk.
