The correct match of the group reagents in List-I for precipitating the metal ion given in List-II from solutions, is. List-I: (P) Passing H₂S in the presence of NH₄OH; (Q) (NH₄)₂CO₃ in the presence of NH₄OH; (R) NH₄OH in the presence of NH₄Cl; (S) Passing H₂S in the presence of dilute HCl. List-II: (1) Cu²⁺; (2) Al³⁺; (3) Mn²⁺; (4) Ba²⁺; (5) Mg²⁺.
