  2. Iron(II) fluoride - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_fluoride

    The anhydrous salt can be prepared by reaction of ferrous chloride with anhydrous hydrogen fluoride. [12] It is slightly soluble in water (with solubility product K sp = 2.36×10 −6 at 25 °C) [13] as well as dilute hydrofluoric acid, giving a pale green solution. [1]

    en.wikipedia.org/wiki/Ferrocyanide

    Ferrocyanide is the name of the anion [Fe() 6] 4−.Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6.

  5. Nernst equation - Wikipedia

    en.wikipedia.org/wiki/Nernst_equation

    In electrochemistry, the Nernst equation is a chemical thermodynamical relationship that permits the calculation of the reduction potential of a reaction (half-cell or full cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the redox reaction, and activities (often approximated by concentrations) of the chemical species undergoing ...

    The thermochemical two-step water splitting process uses two redox steps. The steps of solar hydrogen production by iron based two-step cycle are: {+ + + + + ()Where M can by any number of metals, often Fe itself, Co, Ni, Mn, Zn or mixtures thereof.

  8. Ionic radius - Wikipedia

    en.wikipedia.org/wiki/Ionic_radius

    Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.
