H2O

[Sophia Dinh 1D]

When do we include H2O and when do we exclude it from the ice table

[Jorja De Jesus 2C]

You don't include H2O if it is in solid or liquid form. Solids and liquids are not counted in ICE tables.

[Sydney Pell 2E]

Solids and liquids are not factored into the calculations for equilibrium constants (and therefore in ICE tables) because their concentrations are not changing.

[Alice Ma 2K]

If H2O is in the gaseous form, it should be included. But if it's in the liquid or solid form, then it doesn't need to be included.

[Jacob Villar 2C]

H2O is usually in liquid form, and liquids and solids are not included in ICE tables.

[SVajragiri_1C]

You don't include any reactant or product in the liquid of solid form when writing out the equation, including H2O.

[EllieSchmidtke_4I]

H2O should only be included if its in gaseous {H2O(g)} form.

[Emily Lo 1J]

You don't include water into your ice table because it's a liquid and when writing the equilibrium constants out, you disregard the liquids.

[Ellen Amico 2L]

You never include solids or liquids in the ICE table or equilibrium constants. If it's gaseous or aqueous, then it's included. In the case of H2O, the only time you would include it is if it's H2O(g).

[Madeline Ogden 3B]

H2O should only be included in an ICE table if it's in gaseous form. We also disregard liquids and solids when making ICE tables due to the fact that there concentrations do not change.

[Sam_Marasigan_3D]

I believe that we omit H2O in the ICE table due to its liquid state. The concentration does not change.

[Margaret Wang 2D]

If it's in the liquid state it is considered a solvent/pure liquid, so no. However, if it is a gas (g) then it needs to be included.

[Jack_Pearce_2H]

H20 can be omitted from the ice stable but if it is in gaseous form it typically needs to be included

[Karl Yost 1L]

Water is omitted from Kc expressions when it is a solvent (i.e. exists as a liquid), as it does not change concentrations. If it exists in gaseous form, include it in the ICE table, in Kc expressions etc.

[DMaya_2G]

Only include H2O when it is in gas form, but not when it is in solid or liquid form.

[apurva-3E]

Exclude it when it's a solid or liquid.

[derickngo3d]

Pure substances and solvents are not included in ICE tables.

Hope this helps!

[Kimiya Aframian IB]

When do we include H2O and when do we exclude it from the ice table

Hi! H20 is only included in the ICE table and K calculations when it is in the gas or aqueous form. This rule also applies for other reagents. Hope this helps!

[Sarah_Hoffman_2H]

Like others have stated, basically H2O is only included if it is in the gas phase.

[RyanKopeikin_2I]

Water would not be included in the equilibrium constant (K) if it is in solid or liquid form. Liquids (solvents) and solids are so abundant in a chemical reaction that their molar concentrations do not change significantly during the reaction. Hopefully this reasoning helps a bit :)

[Adrienne Yuh 2B]

Solids and liquids in general aren't included in equilibrium.

[Joshua Swift]

There is no need to have the H₂O because you don't include any solids or liquids.

[Morgan Gee 3B]

Depending on the state/phase of water, we either include or don't include it in the equilibrium constant or reaction quotient. If it is considered a liquid or solid, we would not consider it, similar to other liquids and solids. However, if it is gaseous, we would include it. It would not be aqueous as aqueous is defined as being dissolved in water, and water dissolved in water would just be liquid water.

[Alexandra Salata 2L]

Like other compounds and elements, you do not include water if it is in solid or liquid phase in your expression. Only when H20 is in the gas phase will you be able to include it.

[Andersen Chu 2H]

Usually H20 is the solvent and since there is so much of it and so little of it is reacting, the concentration is basically the same so you can just leave it out of the equation

[Joel Meza 3I]

Solids and liquids are omitted, so only H2O as a gas should be included.

[Kat Stahl 2K]

When H20 is in solid or liquid form so ice or water it will not be included, only the gas will be included in ICE

[Brandon Gruender 3F]

The only time that this is included in the table is when it is in gas (g) form. The compound is not included if it is in liquid or solid phases.

[Jerry_T]

You would only include H₂O when it is in a gaseous phase.

[Brian Nguyen 2I]

H2O is not included because solids and liquids are not included in equilibrium equations. The only exception would be if H2O was a gas.

[DominicMalilay 1F]

Only include it for gases because solids and liquids are not a part of the ice table!

[Ke Huang 2G]

We only include it when they are gases, not solids or liquids

[Bai Rong Lin 2K]

You do not include it when its solid or liquid, only include when it is gas.

[Justin Zhang_1A]

You only need to include H2O if it as a gas, but you can omit it when it is in a solid or liquid state.

[Mina Tadros 3L]

You only include H2O in the equilibrium constant if it is a gas. If it is a solid or a liquid, you do not include it.

[LeahSWM 2E]

H2O is only included when it is in a gaseous phase!

[Jared Limqueco 3E]

Include it only when it's in a gaseous state.

[Daniel Hernandez 1G]

You wouldn't include H20 in the presence of a solid or liquid.

[Jaclyn Schwartz 1I]

H20 is only included if it is in gaseous form. Other wise, in liquid or solid, it isn't needed to be included.

[John Calonia 1D]

In acid and base reactions where it is reacting with water, the water is in such excess that it is considered pure so it is not included in the calculations for chemical equilibrium constants.

[Minh-Thy Vo 3D]

H2O is only included when it's denoted as a gas. If it's a solid or liquid, it won't be included.

[Gabriel Nitro 1E]

Hi,

We would only include H2O in the gaseous phase, as in the equilibrium constant.

We would not include H2O in the solid or liquid phase as they are pure substances.

Hope this helps! :)

[Libby Dillon - 1A]

H20 is unique in that it sometimes plays a role in equilibrium concentrations and other times it does not. When H20 is in a gaseous state, include it in calculations. When H20 is in liquid form, omit it from any concentration equations. This is because liquids do not technically have a concentration and therefore are not included when finding K.

[DMaya_2G]

H2O is only considered when it is a gas, and not a solid or a liquid.

[Ariel Guan 1H]

If H2O is a liquid or solid, you wouldn't include it. Only include H2O if it is in its gaseous form
