### aqueous elements in eq calculation

I know we do not include solids or liquids in the Kc calculation but do we also not include aqueous solutions? Could someone clarify this for me?

No you would include aqueous molecules in the equilibrium equation since you are able to calculate concentrations from them.

Hope that helps!

We don't include solids and liquids in equilibrium constants because they don't affect the reaction reaching equilibrium. Equilibrium constants depend on the pressure of gases and concentrations of aqueous solutions in the reaction.

Aqueous solutions would be included in the equilibrium equation because these effect the value of K but solids and liquids aren't included because they don't affect K in any way.

yes aqueous solutions are included in eq calculations

included: (g), (aq)
not included: (l), (s)

### Re: aqueous elements in eq calculation

Solids and liquids like water are not included in the equilibrium calculation. Only gas or aqueous in the reaction are counted for. This is the same rule that applies when using the ICE tables and even with Le Chatelier's Principle because changes in the concentration of a liquid or a solid DO NOT affect or create a shift in the direction of a reaction.

### Re: aqueous elements in eq calculation

There are four main "states": solid, liquid, gas, and aqueous. In the equilibrium equation, you would include the gases and aqueous solutions, but you would exclude solids and liquids.

### Re: aqueous elements in eq calculation

This is how I've been applying it, but correct me if I'm wrong: Solids and liquids are not included in equilibrium constants. Aqueous elements (aq) are included to find Kc, and gases (g) are included to find Kp.
