Le Chatelier's Principle with H2O

[Irene Kang 3F]

Does H2O or pure solids/liquids affect Le Chatelier's? Do we count them in like if a different reactant increased in concentration would H2O(if it were a reactant) decrease or would we not count this as part of the reaction?

Since Le Chatelier's Principle accounts for the effects on equilibrium, I do not believe that H2O plays a role of influence. It would only consider aqueous or gaseous phases.

[Jessica Arcos 2H]

You wouldn't consider pure solids and liquids because they don't significantly change the equilibrium constant.

Hi! I don't believe you would consider pure solids and liquids as a part of it because they do not really affect equilibrium constants. Hope this helps!

[Kaitlyn_Urquilla_1I]

Hi! You would not consider pure solids or liquids since they do not really affect equilibrium constants and Le Chatelier's Principle is for equilibrium.

[Symphony Jackson 3K]

Hi! You would not really consider solids or liquids in an equilibrium problem because their concentrations stay constant throughout the reactions.

[Gianna Sciole 2F]

you would not consider pure liquids or solids when discussing le chatelier's principle. this is because they are insignificant to the equilibrium constant. however, additionally, when speaking of changes in partial pressure, you also would not need to consider the addition or removal of inert gasses because they do not have a significant effect on the equilibrium constant as well. this is because inert (or noble) gasses rarely react and would likely be present, just not as part of the reaction.

Pure solids and liquids are omitted when calculating Le Chatelier's Principle since do not significantly affect equilibrium constants. Therefore, H2O will not affect Le Chatelier's. Only include molecules in aqueous or gaseous phases when doing your calculations.

Since H2O, pure solids and liquids are not counted in the equilibrium constant K, by the same logic, you wouldn't count these for Le Chatelier's problems. I think of it like we don't count the H2O in aqueous media separately, so it isn't factored into the Le Chatelier's principle.

No solids and liquids are not included because their changes are negligible and therefore can be considered 0 change.
