Original Synthesis of Cadmium Nitrate Tetra-Hydrate
Cadmium nitrate tetra-Hydrate is an inorganic compound from the family of compounds with the general formula Cd (NO3)2.XH20, where X=4, hence the molecule has four molecules of water of crystallization in its structure. It exists as a salt but in its anhydrous state, it is known to be a volatile substance. It is a colorless substance as are all the compounds in the family of cadmium nitrates. Cadmium nitrate is a colorless, crystalline, inorganic compound that forms the toxic fumes produced when cadmium oxides are heated. It is an odorless white solid that is more dense than water.
Cadmium nitrate is prepared by first dissolving the metal cadmium

When hydrogen sulfide gas is bubbled through a slightly acidified cadmium nitrate solution, a yellow substance- cadmium sulfide is formed (Karl‐Heinz and Magnus 37). With heating until boiling point, a red refinement of the sulfide is achieved. (Karl‐Heinz and Magnus 27). Qisheng, et al (256) explains how a calcium hydroxide precipitate is produced from the mixing of caustic soda solution with cadmium oxide.
Cadmium nitrate is a highly water-soluble crystal structure. It is a cadmium source with applications mostly compatible with acidic conditions. All nitrates salts of these metals can be classified as inorganic salts made up of the combination of a specific metal cation and an anion derived from a nitrate. The nitrate anion has an equivalent of one negative charge. The nitrate component of the compound is a polyatomic and univalent ion composed of one nitrogen atom which is ionically bound to three atoms of oxygen (Karl‐Heinz and Magnus 78). The formula is NO3 and has a total molecular weight of 62.05 grams (Karl‐Heinz and Magnus 56). All known nitrate salts are generally found to be water soluble (Karl‐Heinz and Magnus 57). They also act as oxidizers in redox reactions (Karl‐Heinz and Magnus 75). When synthesized with hydrocarbons, the compounds containing nitrates can

Solutions of cadmium nitrate are average to highly concentrated liquid solutions of cadmium nitrate, they can also be used as an excellent raw material in producing the cadmium nitrate powder for applications that require materials that are solubilized. Public manufacturers and sellers such as the American Elements are able to prepare homogenously dissolved solutions for customers at concentrations of their choosing or to the highest acceptable stoichiometric concentrations. They are then available in small packages of 55-gallon drums, and much lesser liquid
