Solvents are not included in the reaction quotient or equilibrium constant, because there is way for you to measure the concentration of a pure solid displaced in some liquid. Just know that liquids and solids are not used or even considered when doing ice boxes or calculating the equilibrium quotient.

Whenever solvents are liquids or solids they are not in included in equilibrium constant expressions. This is because the change in solvent concentration is insignificant.
