INFORMATION TAKEN FROM WEBSITES:–

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(SO4)2·12H2O. However, any of the compounds with the empirical formula AB(SO4)2·12H2O are considered to be an alum. Sometimes alum is seen in its crystalline form, although it is most often sold as a powder. Potassium alum is a fine white powder that you can find sold with kitchen spices or pickling ingredients. It is also sold as a large crystal as a “deodorant rock” for underarm use.

FROM WKIPEDIA

Potassium alumpotash alum, or potassium aluminium sulfate is a chemical compound: the double sulfate of potassium and aluminium, with chemical formula KAl(SO4)2. It is commonly encountered as the dodecahydrate, KAl(SO4)2·12H2O. It crystallizes in cubic structure with space group P a -3 and lattice parameter of 12.18 Å[4]. The compound is the most important member of the generic class of compounds called alums, and is often called simply alum.[5]
