[edit] Heptahydrate
I have conflicting data on the temperature at which the heptahydrate loses water. Lange's gives 33.4°C, which seems reasonable for a substance that effloresces at room temperature. 44th CRC gives 150°C, but I expect that this is in an atmosphere of pure steam. In reality there are two variables controlling whether heptahydrate loses water. One is temperature and the other is the ambient vapor pressure of water. Karlhahn 03:22, 23 August 2006 (UTC)
