When calculating the value of K, do we keep water if it is in a gas phase? I know it is not included in the K calculation if is a liquid since it is a solvent.

Correct. If the equation says that H2O is a (g) gas then we include it in K. Anything that is a solid or a liquid we do not include in K. We only include gases and aqueous solutions.

If a product or reactant is a solid or liquid, is its contribution to the K calculation automatically 1?

So basically a solution cant be completely basic or acidic, since the [OH] or [H3O] cant equal zero, right?
