Solubility & Saturation

Why does sugar dissolve better in hot tea? Set a solubility curve and see exactly how much dissolves — and when crystals start to form.

Salt added (g/100mL)

Most salts dissolve more readily as water warms. Below the solubility curve everything dissolves; above it, the excess stays as solid crystals. Cooling a saturated solution forces crystals out — the basis of recrystallization. Educational tool.

Governing equation

S (T) = S_{0} + k T = 30 + 1.2 \times 40 = 78 g/100mL

Reading this result: At 40°C only 78 g/100mL will dissolve, so 2 g stays as solid — the solution is saturated and sitting on the curve.

How it works

A solubility curve shows the maximum a solvent can hold at each temperature. Below the curve everything dissolves; above it the excess remains as solid. Cooling a saturated solution pushes it above the curve, forcing crystals out — the principle behind recrystallization and rock candy. Educational tool.

Frequently asked questions

Is this solubility curve simulator tool really free?▾

Yes. Solubility & Saturation runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.

Do I need to install anything?▾

No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.

Can I save or share my simulation?▾

Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.

How accurate are the results?▾

The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
