How Is Zn(NO2)2 Synthesized Or Prepared?

Zn(NO2)2 can be synthesized by reacting zinc oxide (ZnO) with nitric acid (HNO3). The reaction occurs as follows:

ZnO + 2HNO3 → Zn(NO2)2 + H2O

To prepare Zn(NO2)2, first, a solution of nitric acid is prepared by dissolving it in water. Then, zinc oxide is slowly added to the solution while stirring continuously until it dissolves completely.

The resulting solution is then filtered to remove any impurities and then evaporated to dryness to obtain the solid Zn(NO2)2. The purity of the compound can be confirmed by analyzing its melting point and chemical composition using techniques such as differential scanning calorimetry (DSC), infrared (IR) spectroscopy, and X-ray diffraction (XRD).
