JEE Main 2024 Chemistry question
Molar ionic conductivities of divalent cation and anion are 57 S cm mol and 73 S cm mol respectively. The molar conductivity of solution of an electrolyte with the above cation and anion will be:
Answer: (B)
Solution
Taking the electrolyte as a 1 : 1 salt of the two ions (each being divalent), Λ = 57 + 73 = 130 S cm² mol⁻¹, as the key does.
