Chemistry - Salt Analysis Question with Solution | TestHub

Question Explanation:

Match cations (Group I to IV) to their group reagents.

Concept: Basic Radical Group Reagents.

Solution:

${\mathrm{NH}}_4{}^{+}$and ${\mathrm{K}}^{+}$ions can be distinguished by

(1) ${\mathrm{Na}}_2\left[\mathrm{Pr}+{\mathrm{Cl}}_6\right]+\stackrel{{\mathrm{K}}^{\oplus }/{\mathrm{NH}}_4^{\oplus }}{\to }$ white ppt with both ions

(2) ${\mathrm{Na}}_2\left[\mathrm{Pr}+{\mathrm{Cl}}_6\right]+\stackrel{{\mathrm{K}}^{\oplus }/{\mathrm{NH}}_4^{\oplus }}{\to }$ white ppt with both ions

 only (C) & (D) options are used for distinction test rest are not.
