 HOMOGENEOUS MIXTURES
HETEROGENEOUS MIXTURES The prefixes "homo"- indicate samenessThe prefixes: "hetero"- indicate difference.A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions.
A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
Graphic on the left of "Dancing Raisins" shows liquid, solid, and gas substances in a heterogeneous mixture.
Particle size distinguishes homogeneous solutions from other heterogeneous mixtures. Solutions have particles which are the size of atoms or molecules - too small to be seen.
A colloid is a homogeneous solution with intermediate particle size between a solution and a suspension. Colloid particles may be seen in a beam of light such as dust in air in a "shaft" of sunlight. Milk, fog, and jello are examples of colloids.
In contrast a suspension is a heterogeneous mixture of larger particles. These particles are visible and will settle out on standing. Examples of suspensions are: fine sand or silt in water or tomato juice.Corn oil is homogeneous, White vinegar is homogeneous. A sugar solution is homogeneous since only a colorless liquid is observed. Air with no clouds is homogeneous.For example beach sand is heterogeneous since you can see different colored particles. Vinegar and oil salad dressing is heterogeneous since two liquid layers are present, as well as solids. Air with clouds is heterogeneous, as the clouds contain tiny droplets of liquid water.

Heterogeneous mixture

It is a mixture in which the particle or substances are not evenly spread or distributed as shown in the above figure. This type of mixture can be easily converted to their original shape through chemical processes. Heterogeneous mixtures are also called as suspensions or colloids. The word ‘hetero’ means different.

For example- Mud is a good example for colloids. If you mix some mud with water and keep it for few days, you can see that mud gets settled in the bottom of the container. Hence this shows that mud and water form a heterogeneous mixture. This kind of suspensions or colloids are visible to the naked eye.

Homogeneous mixture

As the word ‘Homo’ means same, homogeneous mixture are those substances in which the particles are uniformly distributed within the container. The size and shape of every particle remains same in this case. Homogeneous mixture are also known as solutions.

A good example for this kind of mixture is steel. In steel, the iron and carbon are evenly distributed which makes it a homogeneous mixture. These are not visible to the naked eye.
