Finding K: liquids and aqueous
Why do we keep aqueous solutions in the concentration equations and not liquids?

Re: Finding K: liquids and aqueous
Aqueous solutions have a defined concentration. For example 10 moles of salt in one liter of aqueous solution is 10M concentration. However, a liquid by itself cannot be measured in concentration. If you had just water, you would not be able to write it in terms of a concentration.

Re: Finding K: liquids and aqueous
While liquids do not have a defined concentration (molarity), aqueous solutions do.
Re: Finding K: liquids and aqueous
Liquids are pure substances and therefor cannot have a concentration. To have a concentration there needs to be a solute in a solvent, 2 substances, liquids are only 1 substance.

Re: Finding K: liquids and aqueous
Yes, this is the same case for solids. Their concentrations do not change.
Re: Finding K: liquids and aqueous
To clarify,
solids are not included in the K expression because they don't necessarily have a "concentration," and liquids are not included because they consist of a pure substance?
Is this thinking correct?
