Water in Equilibrium Constant Eq.

Postby Zoya Mulji 1K » Thu Jan 16, 2020 4:51 pm

With acid and base equilibrium reactions, why do you not include water in the equilibrium constant equation?

In acid and base equilibria problems, the concentration of water is in large excess and therefore left essentially unchanged, leading us to omit it from K expressions.

if a different solvent was used, besides water, would it be included in the calculations?

I believe solvents aren't ever included in the equilibrium constant
