CBSE Class 12 · 2011 · Delhi · Redox Reactions and ElectrochemistryVery Short Answer

Express the relation between conductivity and molar conductivity of a solution held in a cell.

Answer: Λ_m = κ × 1000 / C (κ in S cm⁻¹, C in mol L⁻¹).

Solution

Molar conductivity is related to conductivity by

Λ_{m} = \frac{κ \times 1000}{C}

where

κ

is the conductivity in S cm

^{- 1}

and

C

the molar concentration in mol L

^{- 1}

(then

Λ_{m}

is in S cm

^{2}

mol

^{- 1}
