hi guys
Is there any material that soluble in water at ambient or low temperature and insoluble at elevated temperature?

Lots. Most gases. Some solids.

CO2?

[alex00]

which solids? is there any phrase for it?

[alex00]

NH3 has good rate of solubility from ambient T to elevated T. But which solids is there like it?

I am thinking about using it for crystallization. at high T we could dissolving our crystal raw materials (the solid not solved at high T) when the solution cooling down the solid dissolve in to the water and force the crystals out .
I know it`s thermodynamic is important .

Inverted solubility.

Cerium Sulfate. Sodium Sulfate.

[curiouscat]

Calcium Sulfate too I think.

[alex00]

Cerium Sulfate. Sodium Sulfate.

cerium sulfate good but it`s rate is low. and about sodium sulfate it is correct higher than 30C

CaSo4

[alex00]

also MnSO4
