In a conductometric titration, small volume of titrant of higher concentration is added stepwise to a larger volume of titrate of much lower concentration, and the conductance is measured after each addition. The limiting ionic conductivity ( ₀ ) values (in {mS}\,{m}²\,{mol}^{-1} ) for different ions in aqueous solutions are given below: Ions {Ag}^{+} {K}^{+} {Na}^{+} {H}^{+} {NO}₃^{-} {Cl}^{-} {SO}₄²-} {OH}^{-} {CH}₃{COO}^{-} ₀ 6.2 7.4 5.0 35.0 7.2 7.6 16.0 19.9 4.1 For different combinations of titrates and titrants given in List-I, the graphs of 'conductance' versus 'volume of titrant' are given in List-II. Match each entry in List-I with the appropriate entry in List-II and choose the correct option. List-I List-II (P) Titrate: KCl Titrant: {AgNO}₃ (1) (Q) Titrate: {AgNO}₃ Titrant: KCl (2) (R) Titrate: NaOH Titrant: HCl (3) (S) Titrate: NaOH Titrant: {CH}₃{COOH} (4) (5) [JEE Adv 2024 P1]
