Match the List-I with List-II : Cations Group reaction {\P} \to {\Pb}^{2+}, {\Cu}^{2+} (i) {\H}_2 {\S} gas in presence of dilute {\HCl} {\Q} \to {\Al}^{3+}, {\Fe}^{3+} (ii) ( {\NH}_4) _2 {\CO}_3 in presence of {\NH}_4 {\OH} {\R} \to {\Co}^{2+}, {\Ni}^{2+} (iii) {\NH}_4 {\OH} in presence of {\NH}_4 {\CI} {\S} \to {\Ba}^{2+}, {\Ca}^{2+} (iv) {\H}_2 {\S} in presence of {\NH}_4 {\OH} [25-Jan-2023 Shift 1]

Correct Answer is : P→i,Q→ iii, R→ iv, S→ ii

{\P} \to i, Q \to iii, {\R} \to ii, {\S} \to iv

{\P} \to iv, {\Q} \to ii, {\R} \to iii, {\S} \to i

{\P} \to iii, {\Q} \to i, {\R} \to iv, {\S} \to ii

{\P} \to {\i}, {\Q} \to iii, {\R} \to iv, {\S} \to ii
