$Na(NH_4)HPO_4 \cdot 4H_2O$

Vedclass · Answer

(C) The bead test (specifically the microcosmic salt bead test) uses microcosmic salt,which is $Na(NH_4)HPO_4 \cdot 4H_2O$. Upon heating,it decomposes to form a transparent bead of sodium metaphosphate: $Na(NH_4)HPO_4 \cdot 4H_2O \xrightarrow{\Delta} NaPO_3 + NH_3 + 5H_2O$. This sodium metaphosphate bead reacts with metal oxides to form colored beads.
