Double Replacement
Explanation:
Let's consider the following balanced reaction that occurs between aluminum sulfate and tripotassium phosphate.
Al₂(SO₄)₃ + 2 K₃PO₄ ⇒ 2 AlPO₄ + 3 K₂SO₄
This is a double replacement reaction because both salts exchange their cations and anions. So, PO₄³⁻ takes the place of SO₄²⁻ in Al₂(SO₄)₃ and SO₄²⁻ takes the place of PO₄³⁻ in K₃PO₄.
