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 mS m2mol−1 ) for different ions in aqueous solutions are given below:
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.
The limiting ionic conductivity (Λ0) values (in mS m2mol−1 ) for different ions in aqueous solutions are given below:
