Answer:
Double Replacement
Explanation:
Let's consider the following balanced reaction that occurs between aluminum sulfate and tripotassium phosphate.
Alβ(SOβ)β + 2 KβPOβ β 2 AlPOβ + 3 KβSOβ
This is a double replacement reaction because both salts exchange their cations and anions. So, POβΒ³β» takes the place of SOβΒ²β» in Alβ(SOβ)β and SOβΒ²β» takes the place of POβΒ³β» in KβPOβ.
