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 ( \Lambda _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^{2-}_4 \OH^{-} \CH_3\COO^{-} \Lambda_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]
