It is prepared by crystallizing the alum from a concentrated solution containing equimolar amounts of potassium sulfate and aluminium sulfate. It is a colourless, crystalline solid with a sour taste. The crystal of potash alum is octahedral. It is commonly known as ‘fitkari’.
WebPotassium alum, potash alum, or potassium aluminium sulfate is a chemical compound: the double sulfate of potassium and aluminium, with chemical formula KAl(SO 4) 2. The … Alums crystallize in one of three different crystal structures. These classes are called α-, β- and γ-alums. The first X-ray crystal structures of alums were reported in 1927 by James M. Cork and Lawrence Bragg, and were used to develop the phase retrieval technique isomorphous replacement. [22] Solubility [ edit] See more An alum 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, where X is a monovalent cation such as potassium or ammonium. By itself, "alum" often … See more Aluminium-based alums are named by the monovalent cation. Unlike the other alkali metals, lithium does not form alums; a fact attributed to the small size of its ion.
