An alum (/ ˈæləm /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl (SO. 4) 2·12 H. 2O, such that X is a monovalent cation such as potassium or ammonium. [1] . By itself, "alum" often refers to potassium alum, with the formula KAl (SO. 4) 2·12 H. 2O.
Usually, when you hear about alum it is in reference to potassium alum, which is the hydrated form of potassium aluminum sulfate and has the chemical formula KAl(SO 4) 2 ·12H 2 O. However, any of the compounds with the empirical formula AB(SO 4 ) 2 ·12H 2 O are also considered to be alum.
18 Οκτ 2024 · The most important alums are potassium aluminum sulfate, ammonium aluminum sulfate, and sodium aluminum sulfate. Potassium aluminum sulfate, also known as potassium alum or potash alum, has a molecular formula of K 2 (SO 4 )·Al 2 (SO 4 ) 3 ·24H 2 O or KAl(SO 4 ) 2 ·12H 2 O.
9 Αυγ 2023 · The chemical formula commonly used to represent Alum is XAl (SO 4) 2.12H 2 O. Typically, when discussing alum, it commonly refers to potassium alum, a hydrated compound of potassium aluminum sulfate with the chemical formula KAl (SO 4) 2.12H 2 O.
Aluminium powder is powdered aluminium. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s.
The general chemical formula for alum is XAl (SO 4) 2 ·12H 2 O. Alums can occur as minerals. For example, alunite and leucite. Alum crystals are also available in both offline and online markets, such as grocery shops and medical stores or e-commerce websites.
Alum powder is obtained from rock form of alum. Its fine grains are colorless, transparent and have a crystalline structure. It has some unique properties due to which we find so many different uses. Here is a list of properties that will help you to understand its characteristics.
