I need to find the structure of[tex]CuSO_4.5H_2O[/tex], [tex]ZnSO_4.7H_2O[/tex] and [tex]FeSO_4.7H_2O[/tex]. Ive looked at J.D. Lee for them but cant seem to find them, maybe im looking in the wrong place. I cant find something worthwhile on the net either. All I seem to hit are actual pictures of the salts/solutions but not the actual structure. Please help. If you can point out a link or something, Id be really greatful.
