That is probably a better way of putting it, but still, if you evaporate the water away you end up with the exact same thing you started with. Also, just because an equillibrium exists does not mean that it's a chemical reaction. Look at the equillibrium that exists when a substance is boiling. An equillibrium is set up between the liquid phase of the substance and the gas phase. No chemical reaction is occuring at all, but an equillibrium exists. :D

Ahh, but this is not a chemical equilibrium, it is purely physical. You cannot have a Ksp for this reaction.
In catalysis, for example, you reform the catalyst at the end of the reaction. This definitely does not mean that the catalyst did not undergo any chemical reaction, and in fact we know thew opposite is true.
