Aluminum sulfate acidifies the soil because of the sulfate, not the aluminum. Actually, its possible aluminum, being Al+++, could take the place of 3 hydrogen ions (H+), though more likely is it would take the place of a Ca++ and 1 H+.

Alum | chemical compound | Britannica
Alum, any of a group of hydrated double salts, usually consisting of aluminum sulfate, water of hydration, and the sulfate of another element. A whole series of hydrated double salts results from the hydration of the sulfate of a singly charged cation (e.g., K +) and the sulfate of any one of a number of triply charged cations (e.g., Al 3+).Aluminum sulfate can thus form alums with .

How do I use aluminum sulfate in my pool?
Click to see full answer. Also know, what is Aluminium sulphate used for in swimming pools? Alum, short for aluminum sulfate, is a flocculant, meaning that it attracts and traps suspended particles in the water and then sinks them to the bottom of the pool so that these particles can be vacuumed out. The use of alum is more labor-intensive but often gives quick consistent results.
