Difference between Solution, Colloids and Suspension
Solutions, colloids, and suspensions are examples of mixtures of two or more substances. The three types of this mixture have a fundamental difference that we can observe.
What are the differences? Here is the full explanation!
Solution
The solution is a mixture consisting of solutes and solvents. Solvents usually have more amounts than solutes. One example of a solution is a sugar solution.
Sugar has a solid and granular shape. When we put sugar into water and then stir, it will dissolve. We can not distinguish again which ones are sugar molecules and which ones are water molecules. This is because the two substances are mixed with homogeneous.
A mixture of two or more substances that are homogeneous is called a solution.
The solution has a very small particle size (small of 1nm). Therefore, the solution particles can be spread evenly to all parts of the container. This particle size makes the solution stable and the mixed substances will not separate.
Because of the very small particle size, the solution cannot be separated by filtration. The mixed substances from a solution can only be separated by a special technique, eg evaporation.
Colloid
Colloids have a larger particle size than the solution, which is between 1 nm - 100 nm. One example of the colloid is coconut milk which is a mixture of fat and water.
At first glance, it appears that coconut milk is a homogeneous mixture. All parts of the mixture are white. However, if the coconut milk is left for a while or inserted into the refrigerator, the fat will separate from the water where the fat is on top while water is at the bottom.
From the above facts, it can be concluded that colloid is a heterogeneous mixture.
The colloids consist of two phases: the dispersed phase and the dispersing medium. The dispersed phases are solutes which are spread evenly throughout the mixture. While the dispersing medium is a substance in charge of disseminating the solute.
In coconut milk, fat is a dispersed phase while water is the dispersing phase.
Because it can separate itself, the colloid is not a stable mixture. Colloids can be separated using screening techniques. However, the filter used is not an ordinary filter, but an ultrafilter.
Here are some examples of colloids in everyday life:
1. Gel
2. Milk
3. Soap Foam
4. Cheese
5. Fog
6. Butter
Suspension
Suspensions are often also referred to as coarse mixtures. This is because the particle size of the mixed substance is large over 100 nm. Due to the force of gravity, substances with large particle size will be drawn to the bottom of the container and finally settle.
The suspension is also a heterogeneous mixture in which the mixed substances can be clearly distinguished. An example of a suspension is a mixture of sand with water.
Although the mixture has been stirred hard, the sand that is larger particles will soon settle at the bottom of the container. While the water will be at the top. Thus it is certain that the suspension is not a stable mixture.
The mixture of the suspension type can be easily separated using a common filter such as filter paper.
Well, from the brief explanation above of course you have fully understood the difference between solution, colloid, and suspension. Hopefully, the above explanation can be useful and see you again in other articles.
