Aluminum sulfate, often referred to as alum, is a chemical compound with the formula Al 2 (SO 4) 3. It is a white crystalline solid in its anhydrous form and becomes octadecahydrate (Al 2 (SO 4) 3 ·18H 2 O) when hydrated.
Aluminum sulfate has an action similar to that of alum but is more stringent (2). Aluminum sulfate is an aluminum salt composed of aluminum, sulfur, and oxygen, three plentiful elements. Its molecular formula is Al2 (SO4)3 or Al2S3O12 or Al2O12S3.
General Description. Anhydrous aluminum sulfate is a white crystalline solid. Aluminum sulfate is also obtained as an 18-hydrate Al2 (SO4)3.18H2O. Both forms are soluble in water, noncombustible, and nontoxic. The primary hazard is the threat to the environment.
Although aluminum sulfate is an incredibly useful chemical, it can be toxic and can have a negative impact on both humans and the environment if not handled appropriately. Here, we will discuss alum toxicity to humans and the environment. Read more Download the Guide
Aluminium sulfate (anhydrous) is an aluminium sulfate that contains no water of crystallisation. ChEBI Aluminum (Al), also spelled aluminum, chemical element, a lightweight, silvery-white metal of main Group 13 (IIIa, or boron group) of the periodic table.
Aluminum sulfate is a chemical compound that is composed of the following elements: aluminum, sulfur, and oxygen. Aluminum sulfate is categorized as an ionic compound because it is made of...
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 …
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.
Aluminum sulfate can thus form alums with sulfates of the singly charged cations of potassium, sodium, ammonium, cesium, and other elements and compounds. In similar fashion, sulfates of the triply charged cations of iron, chromium, manganese, cobalt, and other metals may take the place of…
The most important alums – potassium, sodium, and ammonium – are produced industrially. Typical recipes involve combining aluminium sulfate and the sulfate monovalent cation. The aluminium sulfate is usually obtained by treating minerals like alum schist, bauxite and cryolite with sulfuric acid.: 767 Types Crystal of potassium alum.
