Q. 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 ?

$Z n^{2 +}$

$F e^{3 +}$

$N i^{2 +}$

$C o^{2 +}$

$Z n^{2 +}, C o^{2 +}, N i^{2 +} = I V^{th} Group$
$F e^{3 +} = II I^{r d} Group$
