FeSO₄(s) → Fe²⁺(aq) + SO₄²⁻(aq)
Explanation:
* FeSO₄(s): This represents solid iron(II) sulfate. The (s) indicates it's in the solid state.
* Fe²⁺(aq): This represents the iron(II) ion (Fe²⁺) dissolved in water. The (aq) indicates it's in the aqueous state (dissolved in water).
* SO₄²⁻(aq): This represents the sulfate ion (SO₄²⁻) dissolved in water. Again, the (aq) indicates it's in the aqueous state.
Important Note: There are actually two common forms of iron sulfate:
* Iron(II) sulfate (ferrous sulfate), which is the one we've represented in the equation.
* Iron(III) sulfate (ferric sulfate), which has the formula Fe₂(SO₄)₃. Its dissolution in water would have a slightly different chemical equation.
