Question : 48

Total: 51

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 ( Λ0 ) values (in mS‌m‌‌2‌mol−1 ) for different ions in aqueous solutions are given below:

Ions	Ag+	K+	Na+	H+	NO3−	Cl−	SO42−	OH−	CH3COO−
Λ0	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: AgNO3	(1)
(Q)	Titrate: AgNO3 Titrant: KCl	(2)
(R)	Titrate: NaOH Titrant: HCl	(3)
(S)	Titrate: NaOH Titrant: CH3‌COOH	(4)
