The structure of iron sulfate consists of one iron ion (FeĀ²āŗ) and one sulfate ion (SOāĀ²ā»). In this compound, the iron ion is positively charged, while the sulfate ion is negatively charged, allowing them to bond together through ionic bonds. The sulfate ion has a tetrahedral shape, where one sulfur atom is centrally located and surrounded by four oxygen atoms. These ions form a crystalline structure when solid, often appearing as blue-green crystals.
To prepare iron sulfate, you can react iron with sulfuric acid. This process involves placing a piece of iron into a container with diluted sulfuric acid. As the reaction occurs, iron dissolves and forms iron sulfate and hydrogen gas. You can observe bubbles of hydrogen gas forming as the reaction proceeds. The chemical equation for this reaction is:
After the reaction completes, you can evaporate the remaining liquid to obtain solid iron sulfate crystals. This method is commonly used in laboratories to produce iron sulfate for various experiments and applications.

FeSOā ā FeĀ²āŗ +SOāĀ²ā»
When exposed to air, iron sulfate oxidizes to form iron(III) sulfate and a brownish-yellow coating of iron(III) oxide. This reaction shows the change in the oxidation state of iron from +2 to +3.
4FeSOā + Oā + 2HāO ā 2Feā(SOā)ā + 2HāO
Iron sulfate reacts with alkalis, such as sodium hydroxide, to form iron(II) hydroxide, which precipitates as a green solid.
FeSOā + 2NaOH ā Fe(OH)ā + NaāSOā
When heated, iron sulfate decomposes to form iron(III) oxide, sulfur dioxide, and sulfur trioxide. This reaction releases gases and changes the chemical composition of iron sulfate.
