The correct match of the group reagents in List-I for precipitating the metal ion given in List-II from solutions, is List-I List-II (P) Passing {\H}_2 {\S} in the presence of {\NH}_4 {\OH} (1) {\Cu}^{2+} (Q) ( {\NH}_4) _2 {\CO}_3 in the presence of {\NH}_4 {\OH} (2) {\Al}^{3+} (R) {\NH}_4 {\OH} in the presence of {\NH}_4 {\Cl} (3) {\Mn}^{2+} (S) Passing {\H}_2 {\S} in the presence of dilute HCl (4) {\Ba}^{2+} (5) {\Mg}^{2+} [JEE Adv 2025 P1]

Correct Answer is : P⟶3;Q⟶4;R⟶2;S⟶1

{\P} \rightarrow 3 ; {\Q} \rightarrow 4 ; {\R} \rightarrow 2 ; {\S} \rightarrow 1

{\P} \rightarrow 4 ; {\Q} \rightarrow 2 ; {\R} \rightarrow 3 ; {\S} \rightarrow 1

{\P} \rightarrow 3 ; {\Q} \rightarrow 4 ; {\R} \rightarrow 1 ; {\S} \rightarrow 5

{\P} \rightarrow 5 ; {\Q} \rightarrow 3 ; {\R} \rightarrow 2 ; {\S} \rightarrow 4
