Solids when using ICE
When we calculate the equilibrium constant I know that we ignore solids and liquids. Do we also do this when using the ICE method? Thank you!

Re: Solids when using ICE
I believe so since you don't have any concentration of solids in the first place.

Re: Solids when using ICE
When using the ICE method, you ignore the concentrations for solids and pure liquids. But you use their stoichiometric coefficients to set up the equation.

Re: Solids when using ICE
So the only things that you would use for the ICE table are aqueous and gases?

Re: Solids when using ICE
Yes. You only use the concentrations of aqueous and gases in the ICE method. Therefore, you ignore the concentrations of the solids and liquids.

Re: Solids when using ICE
Liquids are not compressed by pressure, so it does not change the speed of the reaction. That is why it is not in the equilibrium constant equation.

Re: Solids when using ICE
This is also why you don't include solids in ICE tables. Although they may be mentioned in a rxn, when determining Kc for a given rxn, the concentrations of non aqueous/gaseous compounds is completely irrelevant (as mentioned above). A good example of this is found at https://chem.libretexts.org/Core/Physic ... Ice_Tables where they walk you through the process and give you more in depth reasoning behind equilibrium calculations.
