Guest Ademike Posted February 10, 2005 Posted February 10, 2005 When copper(II)pentahydrate (CuSO4.5H2O) is heated, the deep blue color changes to the white color of the anhydrous salt (CuSO4). Why does this happen?....I know it has something to do with the splitting of d-orbitals....anyone know?
budullewraagh Posted February 10, 2005 Posted February 10, 2005 this should be moved to the chem section:\ the pentahydrate of cupric sulfate is a complex. when it is heated the complex "decomposes" (so to speak), yielding water and the anhydrous cupric sulfate.
chemistry Posted February 11, 2005 Posted February 11, 2005 Read up on the transition metals section of a standard principles of chemistry text. I believe that you are right in saying so that it has to do with crystal field splitting.
