一、基本概念在CuSO4溶波中,加过量的浓氨水就形成一种复杂的化合物[Cu(NH3)4]SO4,溶液颜色由天蓝色变为深蓝色。[Cu(NH3)4)SO4称为络合物,它包括络离子[Cu(NH3)4)42和硫酸根负离子SO-24。络离子的结构如下:
First, the basic concept Dissolved in the CuSO4, plus an excessive amount of concentrated ammonia to form a complex compound [Cu (NH3) 4] SO4, the solution color from sky blue to dark blue. [Cu (NH3) 4) SO4 is called a complex and includes complex ions [Cu (NH3) 4) 42 and sulfate anion SO-24. Complex ion structure is as follows:
