Conductivity and Molar Conductivity
Understand the concepts of specific, molar, and equivalent conductivity, their dependence on concentration, and how to calculate them.
Why this shows up in the exam
Questions often require you to calculate or compare conductivities and understand their variation with dilution.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
The molar conductivity of a 0.5 mol/dm³ solution of AgNO₃ with electrolytic conductivity of 5.76 x 10⁻³ S cm⁻¹ at 298 K is

Consider two solutions: 0.1 M NaCl and 0.1 M CH3COOH. When both solutions are diluted by adding an equal volume of water, how does the change in molar conductivity (Λm) for NaCl compare to that for CH3COOH, and what is the primary reason for this difference?
