EXPLORER Posted September 24, 2004 Posted September 24, 2004 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
Chintamani Posted October 24, 2004 Posted October 24, 2004 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
