What is Fe(NO3)2? Important knowledge about Fe(NO3)2.

  1. Definition of Fe(NO3)2

Fe(NO3)2, also known as Iron(II) nitrate or Nitrate of iron(II), is an unstable and easily oxidized chemical compound. In chemistry, it contains iron in an oxidation state of +2 and nitrate as the anion. In the Fe(NO3)2 molecule, there is one iron atom and two nitrate groups. Each nitrate group consists of one nitrogen atom and three oxygen atoms. The molar mass of Fe(NO3)2 is 241.86 g/mol.

  1. Properties: Fe(NO3)2

Fe(NO3)2 usually appears as light brown crystals, odorless or with a very faint smell. The pH of its solution is weakly acidic. In terms of chemical properties, Fe(NO3)2 easily undergoes oxidative reactions to form Fe(NO3)3.

  1. Common chemical equations of Fe(NO3)2

Fe(NO3)2 can react with various metals, acids, or nonmetals. For example, Fe(NO3)2 can react with sodium hydroxide (NaOH) to produce Fe(OH)2 and sodium nitrate (NaNO3). Besides, it can also react with salts such as sodium sulfate (Na2SO4) to generate iron(II) sulfate (FeSO4) and sodium nitrate (NaNO3).

  1. Synthesis of Fe(NO3)2

Fe(NO3)2 can be synthesized in the laboratory by reacting iron with diluted nitric acid, producing Fe(NO3)2 and hydrogen. Fe(NO3)2 is also produced on an industrial scale, but caution must be exercised in this process due to its unstable nature.
