What is the difference between a unsaturated, saturated, and supersaturated solutions?

What is a solution?
First of all you should know what a solution is. A solution is a mixture of a solvent and a solute. A solvent is a liquid in most cases, and the solute is the powder or dissolving material. So a solution is mixing liquid (water) with the powder (salt or sugar).
Solvent+Solute = Solution

What can be the difference between a regular mixture and a solution?

Heterogenous_mixture.jpgMixtures can have ingredients that don’t deal out but solutions would. For example, if you want to mix coffee and sugar, not all the molecules of the sugar are going to mix with all the molecules of the coffee. For example, 1 molecules of coffee surrounds with 3 molecules of sugar. The ratio for a solution has to be 1 molecule to 1 molecules or 1:1. So, the whole point is that the ratio (1:1) is for every molecule in the solution.

Different Kinds of Solutions

Gases, liquids, and solids can dissolve in a liquid solvent. For example, oxygen is a gas and it can dissolve in water. Another example are sodas. Sodas have gases. In liquid solvents, for example alcoholic drinks or petroleum, there can be different liquid solutes. In alcoholic drinks, ethanol can be the solute. Ethanol is another way to say drinking alcohol. Examples of solid solutes can be polymers, amalgams, alloys, or steel.Liquid,_Solid,_Gas.gif

Unsaturated Solution

Unsaturated solution is when it can still dissolve more solute. Any solution that hasn’t reached yet it’s limit. For example, if you have a glass of water and you pour some salt, it will dissolve immediately. In simple words it’s like if it has “room” for the solute. You can find many examples of unsaturated solution in chemistry labs.

Saturated Solution

Solutions cannot only be liquids but they can be gases too. Another way to call this is saturated point. Saturated point is when no more solute will dissolve in the solvent.With this solution, it depends on the temperature. Some solutes will dissolve at high temperatures, and others solutes will dissolve at low temperatures.
Example: If you have a glass of water and you pour some Ocean Spray powder, the powder will stay on top and will dissolve slowly. Another example would be petroleum.

Supersaturated Solution-

(Karen)
Super saturated is when you put solute in the solvent in excess. When you put the solute in a large amount, it might not dissolve into the solvent. The solvent will not be able to absorb the whole solute, because there is too much.

Example Of Supersaturated

If there is too much solute you will be able to see some of solute. When there is too much solute in a solution that it can't hold more it's called supersaturated. For example, when you have lemonade and you add lots sugar and the sugar won't dissolve anymore, the solution (lemonade) has too much sugar the solute absorbed and it can't dissolve more.
An Example of Super Saturated is that when you make a ‘Ocean Spray’ and the powder stays sitting at the bottom. It means that the water is like super full of absorbing the solute. It can’t absorb no more solute. So, the extra solute just goes to the bottom of the container and stays there resting. Something else that could have solute in excess can be known as concentrated. Another way to remember supersaturated can be as the water is super full of solute, so there is a super amount of solute in the solvent.

Differences Between Each Solution-

Saturated vs Unsaturated-
Saturated is when there is a little bit of solute left that hasn’t dissolved completely in the solvent. Unsaturated can be if there were more solute to put in an unsaturated solvent it would absorb more solute. Saturated is when there is a little bit of solute left that hasn’t dissolved completely in the solvent.

nsaturated can be known also as dilute because there is not much solute in the solvent. If there were more solute to put in an unsaturated solvent it would absorb more solute. Which means that there is a a smaller amount of solute in an unsaturated solution than there is in a saturated solution.

Saturated vs Supersaturated-
The difference between saturated and supersaturated is that saturated has a little bit of solute is left sitting at the bottom. Supersaturated is when there is actually a lot of solute sitting at the bottom of a container that can’t be absorbed no more. So the difference is that supersaturated has more solute sitting at the bottom of a container than a saturated would have.


Unsaturated vs Supersaturated-
The difference is that unsaturated solvent still has capacity to absorb the solute. The supersaturated solution is when there is too much solute in the solvent like stack of solute at the bottom of the solvent. Unsaturated has a dilute amount of solute and supersaturated has a concentrated amount of solute. The difference is that unsaturated solvent still has capacity to absorb the solute. The supersaturated solution is when there is too much solute in the solvent, and the solvent can't absorb more solvent. Which means that there is a stack of solute at the bottom of the solvent for supersaturated.

About Our Demonstration
For our demonstration, we are going to mix different things in front of the class.
For the unsaturated solution we will demonstrate what an unsaturated solution looks like we'll add a small amount of solute in solvent.. For a saturated solution we will do the solution with a reasonable amount of solvent in the solute. Supersaturated solution demonstration will be made with a very large amount of solute in the solvent, so that there will be a clump of solute in so we can show clearly what super saturated is.
