Cadmium Nitrate is a crystalline inorganic compound that is highly soluble in water. It is a source of Cadmium with nitrates and a low pH value. All iron nitrates are inorganic salts of iron supplied as a cation and nitrate as an anion. Its anhydrous form is flexible, but some solid crystals are colorless. Like other cadmium compounds, cadmium nitrate is also called carcinogenic.

Cadmium was discovered and first separated by Karl Samuel Leberecht Hermann and Friedrich Stromeyer in 1817. In its original form, it has the appearance of a blue-gray metal. Cadmium nitrate formula is also called Cadmium (II) nitrate or Cadmium dinitrate formula. It is a colorless inorganic crystalline compound. Produces toxic cadmium oxide fumes in the heat.
Nitrate compounds are usually dissolved in water. Nitrate substances are also a type of oxidizing agent. When mixed with hydrocarbons, nitrate compounds can often burn. Nitrates are excellent precursors for producing computers of the highest purity and specific catalysts and nanoscale materials. Cadmium Nitrate is usually readily available in large quantities. Its high purity submicron and Nanopowder forms can be considered.
IUPAC Name: Cadmium(II) nitrate

We fix it by dissolving cadmium metal or its oxide, hydroxide, or carbonate, into nitric acid and then crystallization. The chemical statistics are:
CdO+2HNO3→Cd(NO3)2+H2O
CdCO3+2HNO3→Cd(NO3)+CO2+H2O
Cd+4HNO3→2NO2+2H2O+Cd(NO3)2
Reactions of Cadmium Nitrate
Heat dissipation at high temperatures produces cadmium oxide and nitrogen oxides. Also, when hydrogen sulfide is transferred to its acid mixture, yellow cadmium sulfide forms. With a solution of caustic soda, cadmium oxide forms precipitation cadmium hydroxide.
