How is the molar conductivity of an elecrolytic solution calculated?

How is the molar conductivity of an elecrolytic solution calculated?

Options

  1. Amolar concentration / electrolytic conductivity
  2. Belectrolytic conductivity x 1000 / molar concentration
  3. Celectrolytic conductivity multiplied by molar concentration
  4. Dmolar concentration / square of electrolytic conductivity x 1000

Correct answer

B. electrolytic conductivity x 1000 / molar concentration

Step-by-step solution

Molar conductivity (\Lambda_m)isdefinedastheconductingpowerofalltheionsproducedbydissolvingonemoleofanelectrolyteinasolution.<br><br>Mathematically,itisexpressedas:<br><br>Λm=κ×1000C) is defined as the conducting power of all the ions produced by dissolving one mole of an electrolyte in a solution.<br><br>Mathematically, it is expressed as:<br><br>\Lambda_m = \dfrac{\kappa \times 1000}{C}

where κ\kappa is the electrolytic conductivity (specific conductance) in S cm−1S \, cm^{-1} and CC is the molar concentration of the solution in mol L−1mol \, L^{-1}.

Thus, molar conductivity is calculated as electrolytic conductivity ×1000\times 1000 / molar concentration.

Answer: electrolytic conductivity x 1000 / molar concentration
