Continue to shake until no more salt will come out of the shaker. What happens to the last several crystals of salt that come out? The sodium ions dissolve while the chloride ions sink to the bottom. The salt crystals react with the water to form a new compound. All of the ions separate from each other and dissolve into the water. The salt crystals don't dissolve in the water and fall to the bottom unchanged.
