The chemical equation FeSO4 + Al(OH)3 -> Al2(SO4)3 + Fe(OH)3

  1. Detailed information about the equation:

    • FeSO4: Iron(II) sulfate, a chemical compound with the chemical formula FeSO4. It often appears as hydrates, especially as “green vitriol” or “blue vitriol”, FeSO4.7H2O.
    • Al(OH)3: Aluminium hydroxide, a white insoluble solid. In nature, it appears as the mineral gibbsite (also called hydrargillite).
    • Al2(SO4)3: Aluminium sulfate, a common chemical compound used in the chemical industry. It is a white, odorless crystalline solid with a sour taste.
    • Fe(OH)3: Iron(III) hydroxide or ferric hydrate, an insoluble compound of iron. It is brown in color and is commonly used in water purification.

  2. Reaction conditions:
    The reaction occurs under normal temperature and pressure conditions.

  3. Reaction process:
    To balance the chemical equation, we have the following equation:
    2FeSO4 + Al(OH)3 -> Al2(SO4)3 + 2Fe(OH)3
    This reaction proceeds from left to right, meaning that iron sulfate and aluminium hydroxide react with each other to form aluminium sulfate and iron hydroxide.

  4. Phenomena that occur:
    When the reaction occurs, the color change is the main sign. Aluminium hydroxide and iron sulfate initially have white and green colors respectively, when the reaction occurs, a brown solid iron hydroxide and a white residue of aluminium sulfate appear.
