  2. Iron(III) chloride - Wikipedia

    en.wikipedia.org/wiki/Iron(III)_chloride

    In this application, an aqueous solution of FeCl 3 is treated with base to form a floc of iron(III) hydroxide (Fe(OH) 3), also formulated as FeO(OH) (ferrihydrite). This floc facilitates the separation of suspended materials, clarifying the water. [10] Iron(III) chloride is also used to remove soluble phosphate from wastewater.

  3. Ferric chloride test - Wikipedia

    en.wikipedia.org/wiki/Ferric_chloride_test

    The sample is dissolved in water, or a mixture of water and ethanol, and a few drops of neutral ferric chloride (FeCl 3) solution, which is prepared by adding de-ionised water. Add sodium hydroxide to the mixture until a permanent brown precipitate is formed.

  4. Sodium fusion test - Wikipedia

    en.wikipedia.org/wiki/Sodium_fusion_test

    The sodium fusion extract is made alkaline by adding NaOH. To this mixture, freshly prepared FeSO 4 solution is added and boiled for some time and then cooled. A few drops of FeCl 3 are added and Prussian blue (bluish green) color forms due to formation of ferric ferrocyanide along with NaCl. This shows the presence of nitrogen in the organic ...

    en.wikipedia.org/wiki/Iron(III)_oxide-hydroxide

    Anhydrous ferric hydroxide occurs in the nature as the exceedingly rare mineral bernalite, Fe(OH) 3 ·nH 2 O (n = 0.0–0.25). [3] [4] Iron oxyhydroxides, FeOOH, are much more common and occur naturally as structurally different minerals (polymorphs) denoted by the Greek letters α, β, γ and δ.

  6. Enthalpy change of solution - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_change_of_solution

    The temperature of the solution eventually decreases to match that of the surroundings. The equilibrium, between the gas as a separate phase and the gas in solution, will by Le Châtelier's principle shift to favour the gas going into solution as the temperature is decreased (decreasing the temperature increases the solubility of a gas).

    These are prepared by evaporation of an HF solution containing Fe 3+ at room temperature (α form) and above 50 °C (β form). The space group of the β form is P4/m, and the α form maintains a P4/m space group with a J6 substructure. The solid α form is unstable and converts to the β form within days.
