The ion with the highest limiting molar conductance at 298 K is
Answer: A
The highest limiting molar conductance belongs to H+.
H+ has a limiting molar conductivity of about 350 S cm2 mol−1 at 298 K, far above any metal ion, because it moves by the Grotthuss mechanism: protons hop from one water molecule to the next along hydrogen bonds instead of the whole hydrated ion moving through the solvent.
Na+ and K+ are around 50 and 74, and even counted per mole of ions, Ca2+ and Mg2+ (about 119 and 106) are far below H+.
