Alum refers to a collection of chemical compounds that are hydrated sulfate salts of aluminum and usually one other metal. Common forms of alum include hydrated potassium aluminum sulfate, ammonium aluminum sulfate, and sodium aluminum sulfate. The different compounds have different functions.
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.
Alum is a granular powder or crystalline mass that is odorless, colorless, and transparent. It has a flavor that is both sweet and astringent. Its molecular weight is 458.28 grams per molecule. Egypt, Italy, England, Germany, and India are the other countries that have alum mines.
alum, any of a group of hydrated double salts, usually consisting of aluminum sulfate, water of hydration, and the sulfate of another element.
Alum, also known as potassium aluminum sulfate, is a naturally occurring mineral compound used across cultures and industries in various ways. The most common type of alum found in kitchen pantries is potassium alum.
Alum is an inorganic compound consisting of water molecules, aluminum, other metals besides aluminum, and sulfates. Alum, in its hydrated state, is classified as a double salt. There are various forms of alum, including Potash Alum, Soda Alum, Ammonium Alum, and Chrome Alum.
Aluminum sulfate, often known as alum, is a chemical compound made up of aluminum, sulfur, and oxygen with the formula Al₂ (SO₄)₃. It is typically found as a white powder or crystal and is commonly used in water purification, paper manufacturing, and dyeing processes.
Aluminium sulfate is sometimes called alum or papermaker's alum in certain industries. However, the name "alum" is more commonly and properly used for any double sulfate salt with the generic formula XAl (SO. 4) 2·12H. 2O, where X is a monovalent cation such as potassium or ammonium.

What Is Alum? Alum is an inorganic chemical compound that is generally made up of water molecules, aluminium or other metals and sulphates. Alum is basically a hydrated double sulphate salt of aluminium. 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 is an inorganic compound composed of Water molecules, Aluminum, other Metal than Aluminium, and Sulphates. Alum is a double salt in the hydrated form. Alum exists in different forms: Potash Alum, Soda Alum, ammonium Alum, and chrome Alum. The general chemical formula for Alum is XAl (SO4)2·12H2O.
