标题Re: [问题] 选择性沉淀过程一问
时间Tue Feb 19 01:14:10 2008
※ 引述《taigoinwo (还是一只幼鼠)》之铭言:
: Which of the following aqueous solutions could be treated by selective
: precipitation process to separate the cation constituents?
: (a) AgN03, NaN03, FeN03
含NO3-、Na+ 盐类易溶於水(请查沉淀表),
Ag-及Fe2+(or 3+)很容易藉由选择性沉淀来分离开。
: (b) NaN03, KN03, LiN03,
1A族、NO3-盐类易溶於水,分不开。
: (c) KCl, NH4OH, NaCI,
(NaCl吧?)
1A族、NO3-、NH4+盐类易溶於水,这也分不开。
: (d)none of the above
: 这题该怎麽解
: 感谢~
查查沉淀表应该可以解得出来。 :)
