We need to know what you are trying to dissolve in water. But in general, gases like oxygen or carbon dioxide are more easily dissolved in water when the water is colder. The reason is that when water heats up, the water molecules move faster and make it more difficult for a gas molecule to be attracted to the faster moving molecules.
Mr. Professor the solubility is low 0.013 g/L at 25 oC according to Wikipedia. There are charts on the internet that show its decreasing solubility with increasing temperature. The secound compound seems to act in the same way but the reason is unknown for me. There is also Ce2(SO4)3.
Great video. Thanks!
You're welcome!
Mr. Professor there are salts that decrease solubility in water with the increase of temperature. What is the reason?

CaCO3 mainly (I know that it has sth. to do with entropy) but also (CH3COO)2Ca. Thank You for the answer in advance.
CaCO3 is not soluble in water.

why doesn't the elements crystalize while cooling?
Really! Thank you.
would you not get 3.8g of salt that also precipitates out when it reaches 0C?
But there is only 10g of salt and all of that will stay since at 0 degree, 100 ml of water can apprx still contain 34 g of salt.
