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

hi guys

Lots. Most gases. Some solids.
CO2?
-
which solids? is there any phrase for it?
-
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.
-
Calcium Sulfate too I think.
-
Cerium Sulfate. Sodium Sulfate.
cerium sulfate good but it`s rate is low. and about sodium sulfate it is correct higher than 30C
-
CaSo4
-
also MnSO4
