Aluminium sulfate is a salt with the formula Al 2 (SO 4) 3.It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water [3] [4] and wastewater treatment plants, and also in paper manufacturing.
One method of eutrophication remediation is the application of aluminum sulfate, a salt commonly used in the coagulation process of drinking water treatment. Aluminum sulfate, or "alum" as it is commonly referred, has been found to be an effective lake management tool by reducing the phosphorus load. [2] Sediment core sampled from a Minnesota lake.
In most industries, the name "alum" (or "papermaker's alum") is used to refer to aluminium sulfate, Al 2 (SO 4) 3 · n H 2 O, which is used for most industrial flocculation [1]: 766 (the variable n is an integer whose size depends on the amount of water absorbed into the
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
It is an evenly balanced mixture of aluminium sulfate and aluminium acetate.It can be used as a mordant, which is a substance used to set dyes on fabrics [3] that typically contains a polyvalent metal ion like aluminium or iron, [4] In mixtures with basic aluminium diacetate or aluminium sulfacetate, aluminium triacetate has been used as a mordant with alizarin dye.

Meanwhile, flocculation is a technique that promotes agglomeration and assists in the settling of particles. The most common used coagulant is alum, Al 2 (SO 4) 3 ·14H 2 O. The chemical reaction involved: Al 2 (SO 4) 3 · 14 H 2 O → 2 Al(OH) 3 (s) + 6 H + + 3 SO 2− 4 + 8 H 2 O
s = 1.3 x 10 −5 M We have calculated the solubility of AgCl in pure water to be 1.0 x 10 −5 M, if we compare this value to that obtained in presence of diverse ions we see % increase in solubility = {(1.3 x 10 −5 – 1.0 x 10 −5 ) / 1.0 x 10 −5 } x 100 = 30% Therefore, once again we have an evidence for an increase in dissociation or ...
