The model distinguishes total added solute, dissolved solute and undissolved excess at a fixed illustrative capacity. Their counts obey conservation. Real solubility depends on chemical identity and conditions, and saturation reflects a dynamic balance rather than particles stopping all motion. Marker movement visualises dispersion but does not reproduce molecular structure, hydration shells or actual equilibrium measurements.

The interactive activity is loading.
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.
