Hi..I have an urgent and a good question ( sorry for this ).We all know that salts dissolve faster in the presence of growing heat ( increase ), but when it comes to CaSO4 and Ca(OH)2 , the opposite is correct.Their solubility decreases when the heat rises !..any idea why ? taking in mind that they are exothermic.

 

Thanks a lot for sharing and help

This phenomenon is known as invert solubility and to the best of my knowledge is

applicable to CaSO4 and not Ca(OH)2 ; which is partially soluble in water
