Vedclass · Answer

(C) The bead test (specifically the microcosmic salt bead test) is used in the qualitative analysis of inorganic substances to identify metal ions. The reagent used for this test is microcosmic salt,which is sodium ammonium hydrogen phosphate tetrahydrate,represented by the formula $Na(NH_4)HPO_4 \cdot 4H_2O$. Upon heating,this salt loses water and ammonia to form sodium metaphosphate $(NaPO_3)$,which then reacts with metal oxides to form colored beads.

Which of the following salts is used in the bead test for the qualitative analysis of inorganic substances?
