SUMMARY

The discussion centers on the behavior of saturated solutions in equilibrium, specifically regarding the addition of salt. It is established that adding more salt to a saturated solution does not increase the amount of dissolved salt due to Le Chatelier's principle, which states that a system at equilibrium will adjust to counteract changes. The activity of the solid salt remains constant at 1, indicating that the saturation point is reached regardless of the solid's quantity. This understanding clarifies misconceptions about the relationship between solid quantity and solubility in saturated solutions.

Since saturated solutions are equilibriums, why does adding more salt into the solution not increase the amount of dissolved salt? Le Chatelier's principle state that if there is a change in a equilibrium, the equilibrium moves to counteract the change. I know my statement is wrong but I don't know why because it fits with the principle fine (I think).

Activity of the solid is always 1, it doesn't depend on the solid amount.
