Potash Aluminium Sulphate is an inorganic compound. It is the double sulphate of aluminium and potassium with molecular formula KAl(SO4)2. It is often experienced as dodecahydrate. In an alkali/base solution Potassium Aluminium Sulphate is crystallized as a cubic structure but when comes in contact with the neutral solution, its crystallization is like an octahedral structure. It has its other names or maybe synonyms like Potash-Alum, Burnt Potassium-Alum, and Aluminium Potassium Disulphate. Alum of potassium and aluminium is the most significant member of the generic class, which plays a vital role in chemical compounds. Alum of potassium and aluminium with sulphate with ratio 1:1:2 is metal sulphate. It is commonly referred to as “Fitkari”.
Potassium Aluminium Sulphatee is used widely in various fields of daily life:-
Industrially, today Potassium Aluminium Sulphate is produced by adding Aluminium sulphate in potassium sulphate solutions (concentrated form).
Potash Aluminium Sulphate is highly soluble in water but non-soluble in ethanol and acetone. On heating, it turns to red color and forms a porous thus called burnt alum.
It is large, hard, stable, and transparent crystalline fragments or powder.
