Question

For which electrolyte $\alpha =\frac{{\lambda }_{\sigma }}{{\lambda }_{\infty }}$ doesn't hold good?

• A. $C{H}_{3}OH$
• B. $HCl{O}_4$
• C. $HCOOH$
• D. $NaN{H}_2$

Answer 1

Answer: (D)

$NaN{H}_2$

We have,

$\alpha =\frac{{\lambda }_{\sigma }}{{\lambda }_{\infty }}$ hold good only for those who have the property to give $H^{+}$ ion, or acids

but $NaN{H}_2$ is a strong base

so, $\alpha =\frac{{\lambda }_{\sigma }}{{\lambda }_{\infty }}$ does not hold good.
