Question

Which ions has exceptionally higher ${\lambda }^{\infty }$ value?

• A. $H^{+}$ and $O{H}^{-}$ in $H_{2}O$
• B. $K^{+}$
• C. $N{H}_2^{-}$ and $N{H}_4^{+}$ in $N{H}_3$
• D. $C{l}^{-}$

Answer 1

Answer: (A), (C)

The correct options are
A $H^{+}$ and $O{H}^{-}$ in $H_{2}O$
C $N{H}_2^{-}$ and $N{H}_4^{+}$ in $N{H}_3$

$H^{+}$ and $O{H}^{-}$ in $H_{2}O$ have exceptionally higher ${\lambda }^{\infty }$ value

Similarly, $N{H}_2^{-}$ and $N{H}_4^{+}$ in $N{H}_3$ have exceptionally higher ${\lambda }^{\infty }$ value

This is because the ions are similar in nature to the solvent.
