Zn(No3)2

The compound Zn(NO3)2 is a white crystalline solid that is composed of one zinc cation (Zn2+) and two nitrate anions (NO3-). It is soluble in water and has a molar mass of 189.36 g/mol.

The structure of Zn(NO3)2 can be described as a three-dimensional network of Zn-O and NO3-O bonds. The zinc cation is coordinated to six oxygen atoms, four of which come from the bidentate nitrate ligands and the other two from water molecules if present in solution. Each nitrate ion contributes one uncoordinated oxygen atom to the network, forming bridges between neighboring Zn centers.

Zn(NO3)2 is commonly used as a source of zinc ions in various applications, such as in the production of galvanized steel and as a nutrient supplement in agriculture. It can also be used as a catalyst in organic reactions, particularly in the synthesis of esters.

When heated, Zn(NO3)2 decomposes to form zinc oxide (ZnO), nitrogen dioxide (NO2) gas, and oxygen gas (O2). This reaction is exothermic and can be initiated by a spark or flame.

Safety precautions should be taken when handling Zn(NO3)2, as it can cause irritation to the skin, eyes, and respiratory system. It is also flammable and should be kept away from sources of ignition.
