equilibrium constants and inputs
When finding Kc, why do we ignore liquids and solids? What values do we assume the concentrations of liquids or solids to be once the reaction goes through? (ie- when we see a liquid in an equation, do we assume its molarity will be almost equal to 1 and that's why we ignore it? and why assume that it's 1?)

Re: equilibrium constants and inputs
Solids don't have concentrations because it doesn't make sense for it to have one. Liquids/solvents in reaction generally do not change much in terms of concentration so we assume that the value stays the same and will be on both sides of the reaction so it has no effect on the equilibrium constant.

Re: equilibrium constants and inputs
Solids cannot have a concentration. Liquids are not included in the equation since their concentration essentially does not change so we leave it out.

Solids don't have a concentration and liquids are considered pure substances and their concentration does not change

We ignore liquids and solids since their concentrations do not change. We can then leave them out of the equations when we are solving for the K value.
