How to use the crystallization recovery calculator
Find how many grams of crystals form when a hot saturated solution is cooled. Enter solubility at hot temperature, solubility at cold temperature, mass of water in the fields above; the crystals recovered, crystal yield from dissolved solute are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “recrystallization yield”, “crystals recovered on cooling”, “solubility difference yield”, “calculate crystallization recovery”, “find crystals recovered”.
Formula
Variables
- S1 — Solubility at hot temperature (g per 100 g water)
- S2 — Solubility at cold temperature (g per 100 g water)
- mw — Mass of water (g)
Worked example
With solubility at hot temperature = 60 g per 100 g water, solubility at cold temperature = 10 g per 100 g water, mass of water = 200 g, the calculator gives crystals recovered ≈ 100 g; crystal yield from dissolved solute ≈ 83.33333 %.
Frequently asked questions
What is the crystallization recovery calculator used for?
Find how many grams of crystals form when a hot saturated solution is cooled. It helps with questions such as “recrystallization yield”, “crystals recovered on cooling”, “solubility difference yield”.
What is the formula for the crystallization recovery calculation?
Crystals recovered (g) = (S1-S2) × mw / 100. Crystal yield from dissolved solute (%) = (S1-S2) / S1 × 100. Here S1 is solubility at hot temperature (g per 100 g water), S2 is solubility at cold temperature (g per 100 g water), mw is mass of water (g).
What inputs do I need for the crystallization recovery calculator?
You need solubility at hot temperature in g per 100 g water, solubility at cold temperature in g per 100 g water, mass of water in g. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the crystallization recovery calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the crystallization recovery result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
