Question

Conductance of 0.1 M KCl (conductivity = x $oh{m}^{-1}c{m}^{-1}$)
filled in a conductivity cell is y $oh{m}^{-1}$. If the conductance of 0.1 M NaOH filled in the same cell is z $oh{m}^{-1}$, molar conductance of NaOH will be :

• A. $0.1\frac{xz}{y}$
• B. $10\frac{xz}{y}$
• C. ${10}^3\frac{xz}{y}$
• D. ${10}^4\frac{xz}{y}$

Answer 1

The correct option is D ${10}^4\frac{xz}{y}$

${\lambda }_{m}forNaOH=\frac{100k}{molarity}=\frac{\frac{1000\times xz}{y}}{0.1}(k=\frac{xz}{y})$
