Question

The resistance of $0.0025 \,M$ solution of $K _{2} SO _{4}$ is $326 ohm$. The specific conductance of the solution, if cell constant is $4 .$

• A. $4.997 \times 10^{-4}$
• B. $5.997 \times 10^{-7}$
• C. $6.997 \times 10^{-4}$
• D. $1.20 \times 10^{-2}$

Answer 1

Answer: (D)

$K =\frac{1}{\rho}=\frac{1}{ R }\left(\frac{ l }{ a }\right) $
$\Rightarrow \frac{1}{326} \times 4=1.20 \times 10^{-2}$
