What Is Alum Stone (Fitkari)? Composition & Uses Explained

Alum, often known as fitkari, is an inorganic compound. Its primary structure is a hydrated double sulphate salt of aluminium. The most common type of alum you might be familiar with is potassium alum, also termed potash alum. Alum can also be found in various other forms, including sodium alum, ammonium alum and chrome alum. These are differentiated by their specific metal ions and respective properties.

Since ancient times, alum uses have included water purification, food preservation, dyeing, and medicinal applications. With such versatility, it’s no surprise that alum benefits hold immense value across multiple industries, including food, cosmetics, and pharmaceuticals.

Alum Stone Chemistry: What Is Potassium Alum?

Breaking down the complex structure of alum stone, its chemical composition can be viewed as XAl(SO4​)₂​⋅12H₂​O. The main components include:

• Aluminium: A trivalent metal that forms the central part of the alum structure.
• Sulphate ions: Two sulphate ions (SO4)₂ are bonded to the aluminium ion.
• Water molecules: Here, “12H₂O” signifies that each formula unit of alum stone uses twelve water molecules which contribute to its hydrated nature.

Properties of Alum

Alum, whether in stone or powder form, possesses several notable physical and chemical properties:

• Appearance: Common alums are usually colourless, odourless, and crystalline. They often appear as a white powder or crystalline solid.

• Solubility: They easily dissolve in water, especially hot water, which aids in their usage across various applications.

• Crystallisation: Alums crystallise in a regular octahedral form when precipitated from aqueous solutions.

• Melting and Boiling Points: Alum’s melting point is approximately 92.5°C, and its boiling point is around 200°C.

• Density: The density of an alum stone is about 1.725 g/cm³.

• Taste: Generally, alums have a sweetish astringent taste and can react with litmus paper. This indicates their acidic nature when dissolved in water.
