Add as
Each press adds or removes the stated amount; the last step stops at the beaker limit.
Before and after
Keep a reference, then try adding water, draining or evaporating.
Why does it change?
Add some solute. Then keep a reference and change only one quantity.
- Concentration c
- mol/L
- Solution volume V
- L
- Total solute
- mol
- Dissolved n
- mol
- Undissolved solid
- mol
c = dissolved n / V
Solubility limit: 5.96 mol/L
Model notes
- The model assumes instantaneous, uniform mixing and dissolution up to each solute’s fixed saturation concentration. It does not simulate dissolution time, temperature or chemical reactions.
- Solid is added in measured amounts at the point of entry into the solution. The solution reaches uniform concentration immediately after each measured addition.
- Colour is a qualitative cue, not a universal concentration measurement. Sodium chloride solution remains almost colourless. Grain shapes and the solid layer are illustrative, not individual molecules or a measured solid volume.
- With no liquid left, concentration is not a liquid-solution measurement; the reading shows “No liquid solution”.
