Vedclass · Answer

(C) The identification of cations in qualitative analysis is based on their group reagents:$1$. Group $III$ cations (like $Al^{3+}$) are precipitated as hydroxides by $NH_4Cl + NH_4OH$ $(A-III)$.$2$. Group $V$ cations (like $Sr^{2+}$) are precipitated as carbonates by $(NH_4)_2CO_3$ in the presence of $NH_4OH$ $(B-IV)$.$3$. Group $IV$ cations (like $Mn^{2+}$) are precipitated as sulfides by $H_2S$ in the presence of $NH_4OH + NH_4Cl$ $(C-I)$.$4$. Group $I$ cations (like $Pb^{2+}$) are precipitated as chlorides by dilute $HCl$ $(D-II)$.Therefore,the correct matching is $A-III, B-IV, C-I, D-II$.

$LIST$-$I$ (Precipitating reagent and conditions)	$LIST$-$II$ (Cation)
$A$. $NH_4Cl + NH_4OH$	$I$. $Mn^{2+}$
$B$. $NH_4OH + (NH_4)_2CO_3$	$II$. $Pb^{2+}$
$C$. $NH_4OH + NH_4Cl + H_2S$ gas	$III$. $Al^{3+}$
$D$. Dilute $HCl$	$IV$. $Sr^{2+}$
