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} $
