The solubility properties of ZnSO 4 AA H 2O system at 25℃ in the whole concentration range were investigated by phase equilibrium method,and the corresponding phace diagram and refractive index diagram were constructed.The results indicate that systems are simple,and do not have new compound.The complexes of Zn(Leu)SO 4·0.5H 2O,Zn(Thr)SO 4·H 2O,Zn(Val)SO 4·H 2O which have not been reported in literature were prepared and characterized.
The solubility of ZnSO 4 Try H 2O System at 25℃ in the whole concentration range have been investigated by phase equilibrium method,and the corresponding equilibrium diagrams have been constrcuted.The result indicates that system is simple and free from any inpurity.The compound of Zn(Try) 2 which is not reported in literatures has been prepared and characterized.
