I'm still confused on why liquids are not included in calculating K while aqueous solutions are. Can someone explain this to me? Thanks!

The change in concentration of pure liquids and solids are insufficient — they essentially remain constant.
Thus, they are not included in equilibrium calculations.

We do not include liquids and solids because by convention the values in the calculation of the K expression change over time. The concentrations of solids and liquids do not change.
