liquids and aqueous solutions

Postby smurphy1D » Thu Jan 09, 2020 9:58 pm

If liquids and solids cant be used to determine k then why can aqueous solutions be used? If aqueous solutions are liquid as well?

Only pure solids and liquids can't be used to determine K. Aqueous solutions on the other hand can be used as they are not pure liquids and since they have a molar concentration.

Aqueous solutions can have their concentrations measured and these concentrations are what allow us to calculate K. However, solids and liquids are in such great excess in solutions where it is too hard to calculate their concentrations hence why they are omitted from the equilibrium constant

K is dependent on concentration.

Aqueous solutions have measurable and changeable concentrations. Liquids don't have significantly changeable concentrations and solids don't have measurable concentrations.
