State
This capstone carries one silver salt through plain-water solubility, common-ion suppression, precipitation prediction, and complexation-driven redissolution, showing that all four are the same Ksp equilibrium viewed under different added species, not four separate topics.
Watch for
Treating common-ion suppression and complexation-driven dissolution as opposite, unrelated facts about the same salt, rather than as the identical Q-vs-Ksp test applied to a lowered and then a raised free-ion concentration, misses the single mechanism connecting all four stages.
