The equation FeSO4 + Ba(OH)2 -> BaSO4 + Fe(OH)2

  1. Detailed information about the equation FeSO4 + Ba(OH)2 -> BaSO4 + Fe(OH)2:

    • The above chemical equation is an ion exchange reaction between Iron(II) sulfate (FeSO4) and Barium hydroxide (Ba(OH)2), resulting in Barium sulfate (BaSO4) and Iron(II) hydroxide (Fe(OH)2).

  2. Reaction conditions:

    • The reaction requires appropriate temperature, pressure, and reaction environment. Within the range of laboratory conditions, this reaction usually occurs at room temperature and standard pressure.

  3. Reaction process:

    • When mixing FeSO4 and Ba(OH)2, the ions in these two compounds will exchange positions with each other. Specifically, the Sulfate ion (SO4) from FeSO4 will combine with the Barium ion (Ba) from Ba(OH)2 to form BaSO4. Simultaneously, the Iron ion (Fe) from FeSO4 will combine with the Hydroxide ion (OH) from Ba(OH)2 to form Fe(OH)2.

  4. Observed phenomena:

    • When the reaction occurs, an easily observable phenomenon is the appearance of white precipitate due to the formation of BaSO4. This precipitate is insoluble in water, forming a sediment layer. At the same time, the remaining solution also contains particles of pale blue Fe(OH)2.
