In the wet tests for identification of various cations by precipitation, which transition element cation doesn’t belong to group IV in qualitative inorganic analysis?
(1) $Fe^{3+}$
(2) $Zn^{2+}$
(3) $Co^{2+}$
(4) $Ni^{2+}$
Show Answer
Answer: (1)
Solution:
Formula: Detection Test for Group IV
$ \begin{aligned} & Zn^{2+}, Co^{2+}, Ni^{++}=IV^{ul} \text{ Group } \\ & Fe^{3+}=III^{rd} \text{ Group } \end{aligned} $
