The equation 2FeSO4 -> 2Fe2O3 + 2SO2 + O2

  1. Detailed information about the equation 2FeSO4 -> 2Fe2O3 + 2SO2 + O2 -> :
    The equation shows the decomposition reaction of iron(II) sulfate (FeSO4) to form iron(III) oxide (Fe2O3), sulfur dioxide (SO2) and oxygen (O2).

  2. Reaction conditions:
    This reaction takes place when iron(II) sulfate is heated.

  3. Reaction process:
    When iron(II) sulfate is heated, it decomposes to form iron(III) oxide, sulfur dioxide, and oxygen.

  4. Phenomenon occurs:
    When heated, the iron(II) sulfate changes from blue to brown due to the formation of iron(III) oxide. Simultaneously, we can also smell the characteristic odor of sulfur dioxide.
