Solids do not have concentrations?

Postby Megan_Ervin_1F » Tue Jan 08, 2019 11:32 am

Is the reason that solids are not considered in the equilibrium constant because they do not have concentrations?

yes, solids can be measured by mass and density. There is no such thing as a concentration of a solid.

For similar reasons, pure liquids are not used in the calculation for the equilibrium constant. Only gases and aqueous molecules are used in calculations for K.

Yes, you are correct, solids do not have concentration, and neither do pure liquids; therefore, they cannot be used to calculate for K.
