Alum is a chemical compound of two distinct salts, namely: Sulphate of alumina and sulphate of potassa, or sulphate of alumina and sulphate of ammonia. The last salt is present only in a few varieties, and other specimens contain a soda salt with the salt of alumina, and still others substitute an iron salt for alumina. The following symbols represent the more familiar specimens:Roman or Rock Alum. KO.SO3+Al2O3+24HO. Ammonia Alum. NH~O.SO3+AI2O3+24HO. Iron Alum. KO. SO3+Fe203+24HO. The proportion of water is thus seen to remain uniform through them all, while the characterizing salt is a tersulphate of a sesquioxide.
Rock Alum is the one used in medicine. It is found in a nearly pure state in the volcanic region of Italy, and is purified by solution and subsequent crystallization. The almun ores are certain slaty earths, from which the alum is manufactured by calcination, exposure to the air for three months, and subsequent lixiviation and crystalyzation. Burnt Alum is merely alum deprived of its water by heat. It is powdered and sprinkled upon fungous flesh, acting as a very mild escharotic.

What is the common name for potash alum?
It's commonly called Alum
Is alum the same thing as aluminum chlorohydrate?
Potash alum is another name for potassium alum. Alum is a class of molecular compounds, and included in the class is potassium alum. So, they are not the same thing, but yet very similar in that potash alum is a member of the alum class.
How is alum separated in a mixture of alum and water?
Alum can be separated from a mixture of alum and water through a process called crystallization. When the mixture is cooled or allowed to evaporate, alum will crystallize out of the solution due to its solubility properties. The crystals can then be collected by filtration. This method effectively separates the solid alum from the liquid water.
How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
What is the process of adding alum to water called?

What is the meaning of alum?
A double sulphate formed of aluminium and some other element (esp. an alkali metal) or of aluminium. It has twenty-four molecules of water of crystallization., To steep in, or otherwise impregnate with, a solution of alum; to treat with alum.
What is the theoretical yield of potash alum in preparation of potash alum?
The theoretical yield of potash alum in a preparation reaction can be calculated using stoichiometry and the balanced chemical equation. The amount of potash alum produced will depend on the starting materials used and their quantities in the reaction. It is important to consider the limiting reactant to determine the maximum amount of product that can be formed.

What is difference between feeric alum and non ferric alum?
Ferric alum contains iron, which gives it a yellow color, while non-ferric alum does not contain iron and is typically colorless. Ferric alum is commonly used in water purification and wastewater treatment processes, while non-ferric alum is used in industries like paper manufacturing and tanning.
Which one has a stronger bond salt sugar or alum?
Alum typically has a stronger bond than salt or sugar due to its ionic nature. Alum forms bonds through electrostatic attraction between positive and negative ions, resulting in a stronger bond compared to the bonds formed in salt or sugar molecules.
