A dissolving solid does not vanish. Its particles spread among the liquid particles, too small for us to see separately. The solid is the solute and the liquid is the solvent. A given amount of solvent can dissolve only a limited amount at a fixed temperature. Extra solid may remain at the bottom.

Conserved equal-portion markers and illustrative capacity; not measured solubility or a prediction for every substance.
What to look for
- Dissolved markers remain present
- Extra solid can remain
- More solvent changes the available capacity
Explain what you noticed
A cup can dissolve at most 6 equal portions at this temperature. 8 are added. What is expected at equilibrium?
Keep this idea: Dissolved material remains present, and capacity is finite.
