Dem. 44%Stability
of Nitrates (Ca, Cu, AgJ
D. Cadmium
T o show: The relative heat stability of nitrates of Groups I-A, I-B, and 11-A.
Dem. 452-Zinc
Sulfide Hecied in Air
Materials: Ca(NOa)p, Cu(NO&, AgN03, H-3.
Experiment developed by James A . Young.
Procedure: Separately heat 2 g of each salt in H-3.
T o show: ZnS heated in air gives off SO2 which will decolorize dilute I
