Solutions are homogeneous mixtures. Different types of solutions have solvents and solutes in different phases. Solutes are dissolved in the solvent. In a solution in which carbon dioxide is dissolved in water, the water is the solvent and the carbon dioxide is the solute. Two important concepts in studying chemical solutions are solution concentration and solubility equilibrium. Properties of solutions as a whole are called colligative properties.

Alright. Let's talk about the different types of solutions that you'll see. Don't forget a solution is actually a homogenous mixture meaning that there are actually things within a solution not bonded together. They're just kind of, they're attracted to each other in a way that this makes it the same throughout.

Different types of words that you'll see when you're dealing with solutions are words like solute and solvent. A solute is actually dissolved within the solvent. So whatever is being dissolved is a solute, what it's being dissolved in is a solvent. The universal solvent that is that you'll come across is water and that makes sense since most things are dissolved in water, but there are other types of solutions that you'll see too. One being gas dissolved in gas and that think, you know think about the air we breathe is a mixture of gases. Gas dissolves in liquid and soda is a great example of that, the ga- carbon dioxide bubbles. They're actually gaseous or dissolved in liquid of the soda.

Then we have the liquid dissolved in liquid. Juice is a good example of that. some fresh squeezed juice or something along those lines. You can have solid dissolved in liquid which is like our sugar. Our sugar is going to be our solid form, dissolved in our liquid tea, that would be our. They do actually see this actually quite often solid dissolving in liquid.

Solid dissolving in solid. Steel or any type of metal alloy actually is a mixture of solids.

Gas dissolved in solids like foams or marshmellows. So these are different types of mixtures that you'll see in different mediums that they're actually in, and there are different words that we actually may come across too. Soluble versus insoluble and when you're dealing with double replacement reactions you'll have a precipitate. Precipitates are insoluble meaning they come out of solution. If something is soluble, it means that it's actually dissolved within the solution it doesn't come out, it's still within the solution.

You may see the word miscible versus immiscible. This miscible you can kind of sounds like mixable. That's exactly what it means. If something's miscible, they actually it's something they can mix together. If they're immiscible like oil and water, they are actually not able to mix together. So these two, these four words you might see quite often when you're dealing with types of solutions.
