Question

The conductivity of a 0.01N solution is found to be 0.005 $oh{m}^{–1}c{m}^{–1}$. The equivalent conductivity of the solution will be

• A. $5\times {10}^{-2}Oh{m}^{-1}c{m}^{2}equi{v}^{-1}$
• B. $5\times {10}^{-3}oh{m}^{-1}c{m}^2$
• C. $500oh{m}^{-1}c{m}^{2}equi{v}^{-1}$
• D. $0.5oh{m}^{-1}c{m}^{2}equi{v}^{-1}$

Answer 1

The correct option is C

$500oh{m}^{-1}c{m}^{2}equi{v}^{-1}$

${\Lambda }_{eq}^0=\kappa \times \frac{1000}{N}$

= $\frac{0.005\times 1000}{0.01}=500oh{m}^{-1}c{m}^{2}equi{v}^{-1}$
