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.

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