Aqueous Solution
Professor Lavelle briefly mentioned (aq) while explaining how to balance chemical equations, but what exactly is it and what is it's significance?

Re: Aqueous Solution
The aqueous phase is just what we use to denote a species that is dissolved in water. Most reactions in genchem will take place in the aqueous phase; you just have to know that this means it's in the environment of water as a solvent.

Re: Aqueous Solution
Hi! (aq) stands for aqueous solution. An aqueous solution is a solution in which a given solute is dissolved in water. This term will probably become very relevant when we go over solutions and solubility, but for now, I think it's just helpful to know and be able to recognize the term.

Re: Aqueous Solution
Aqueous refers to something that is dissolved in water. For example, NaCl (aq) would mean a salt solution where salt is dissolved in water.

Re: Aqueous Solution
Just adding on, anytime that you see something like (s), (l), (g), or (aq) to the right of a reactant or product, it is simply there to provide info about what state of matter the reactant or product is in, with (aq) denoting that it is dissolved in water.

Re: Aqueous Solution
Hi!
An aqueous solution is when the solvent within the solution is water and the solute is dissolved within the solution. Regarding the significance, I think it is just another way to describe the substance within the chemical equations. I assume aqueous solutions will pop up more frequently later once we get to later sections such as acids and bases.

Re: Aqueous Solution
an aqueous solution just means that the solute has dissolved in a solution where the solvent is water. It'll become more pertinent when we go over what ions/compounds dissociate in solution.
hope this helps

Re: Aqueous Solution
If something is said to be in aqueous solution, does this mean that it is completely dissolved? I know that usually substances do not 100% dissolve, but if a particular substance is only partially dissolved, would it still be considered in aqueous solution?

Re: Aqueous Solution
I believe that at some point we have to be able to determine a molecule's state of matter, i.e. solid, liquid, gas or aqueous. But I don't remember what information is needed to determine this. How can we determine a molecule's state of matter, and what information is needed to do so?

Re: Aqueous Solution
Hi Molly!! I'm sure Dr. Lavelle and the TAs will go way more in depth on this later as needed, but from what I remember, states of matter are in part defined by how close together the particles in a given entity are. When the particles are super packed together, the object won't change shape, making it a solid; when the particles are still packed together but more loosely, the volume is still consistent, but the shape can change. With gas, the packing of the particles (if you can even really call it packing) is so loose that there is no defined shape or volume at all in most if not all cases. Temperature is a lot of what determines the state of matter that different elements or other compounds take on in different instances :))

Re: Aqueous Solution
Hi!
Aqueous compounds are solutes dissolved in liquid (usually H2O) in reactions. If some compound with (aq) shows up in a chemical equation, know that it is dissolved, and just treat it as a normal reactant. Remember that being aqueous does not mean H2O is a reactant.

Re: Aqueous Solution
The (aq) in a chemical reaction just denotes a species being in an aqueous phase, meaning that it is dissolved in water and the solvent is water.
