Water
I was wondering in class today- is water always a liquid in equations? Can it ever be aqueous? If not, why not?

Re: Water
Water can either be a liquid, solid, or gas. Any substance that has been dissolved in water is said to be in an aqueous state (remember that aqua means water). For water to be in an aqueous state is in itself, a contradiction.

Re: Water
In a couple examples, we've seen water as a gas, such as the reaction of CO(g) + H2O(g) <-> CO2(g) + H2(g). In this case, its pressure would be included in our expression for K or Q.

Re: Water
An aqueous solution is a mixture of something with water, therefore water can be referred to as a solid, liquid, or gas, but cannot be considered aqueous.

Re: Water
There are some cases where water can be a gas or a solid, but it will not be considered aqueous because it cannot be mixed with more water since it already is water.

Re: Water
Like others have said above, water can either be a solid, liquid or gas. However, it will never be aqueous since an aqueous solution is, by definition, one where the solvent is water. Water cannot be dissolved in itself (it cannot be both the solvent and the solute).
