shouldnoteatindat Posted January 10, 2014 Posted January 10, 2014 i recently got some copper sulfate and i am wanting to know how i could make a colored rocket fuel out of it anyone know?
Zumber Posted January 10, 2014 Posted January 10, 2014 Copper sulphate (pentahydrate) is hygroscopic and also for various reasons copper sulphate is not used in fireworks. This link will helpful to you. http://www.amateurpyro.com/forums/topic/2905-pyrotechnic-uses-for-copper-sulfate/
Maserface Posted January 10, 2014 Posted January 10, 2014 make it into copper benzoate and then you might have something
schroedinger Posted January 10, 2014 Posted January 10, 2014 Make some other copper salts out of it. E.g. you could make benzoate, oxide or carbonate

schroedinger Posted January 10, 2014 Posted January 10, 2014 I think he ment coppersulfat (anhydr) is hygroscopic. It turns into the pentahydrate by incorporating 5 molecules of watter into his crystall matrix. The hygroscopicy of copper sulfat is quite different to jormal hygroscopy, as it jncorporates the water into the crystall matrix itself, and not having it staying around.
Mumbles Posted January 10, 2014 Posted January 10, 2014 I'm having a hard time understanding what you mean. However if you're insinuating that when copper (II) sulfate absorbs water from the air to become a hydrate that the water does not coordinate to the copper center, you're flat out wrong. There is a published structure. It coordinates 4 of the 5 waters directly to the metal center equatorially. The 5th is co-crystallized in the unit cell, but not directly associated with the metal.
schroedinger Posted January 10, 2014 Posted January 10, 2014 (edited) Well no, the copper sulfate (anhdrous) is the white stuff, CuSO4. It doesn't contain any water. It absorbs water to become the pentahydrate CuSO4 *5 H2O. This is better writen to be [Cu (H2O) 4] SO4 *H2O, as it coordinates 4 of the Water moleculs direcgly onto the Copperion.The thing i really wanted to describe easy, is the That the water of crystallization behaves quite different in coper sulfatethen in most substances, as it becommes part of the crystall structure itself. So it's the difference between lattice water and coordinsted water Edited January 10, 2014 by schroedinger
