Compare the same number of solute markers before and after dissolving. Some leave the solid group and become dispersed through the solvent, but they are still present. Stirring can help a system approach its limit faster; it does not remove that limit. Adding more solvent can allow more solute to dissolve under otherwise unchanged conditions.

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.
