solids and K

[Jasmine W 1K]

I am confused about why we don't include the solids when calculating K because they are included within the reaction.

[Shivam Rana 1D]

Solids are not in solution because they are not dissolved, and thus there exists no concentration for solids. solids function as a pure substance

[ShastaB4C]

Solids don’t have concentrations or partial pressures, so it can’t be calculated in K.

[Ying Yan 1F]

We don't included solids and pure liquids when solving for K because they don't have affect the concentration of the other reactants and products and does not exhibit a partial pressure. Hope that helps!

[Pablo 1K]

There are no solids for concentration, that would the be pure substance.

[Vincent Leong 2B]

Their concentrations just don't differ when transitioning from the initial to equilibrium. In essence, if you were to include them into the K constant, it would essentially be 1 or negligible.

[Angela Prince 1J]

solids do not have concentration or partial pressure.

[Jaklin Astvatsatryan]

Basically, when you add a solid to a solvent, like water, it just sits at the bottom (it doesn't dissolve), therefore it has no concentration and doesn't affect the overall equilibrium constant.

For not including liquids and solids, what if there is H2O as a gas? When I see that I'm worried that there is a typo.
Also, I've noticed a few typos in the textbook so far about figure numbers which is frustrating.
