Potash Alum occurs naturally and is chemically potassium aluminium sulphate, a white crystalline compound typically used as a mordant for dyes and fire proofing along with other industrial applications. Alum yields about 13% alumina (Al 2 O 3) on cotton.Addition of alkali to alum solution produces basic aluminium sulphate, which is used as a mordant. Write balanced chemical equations to show the reactions of the following : 1. Look up the actual value for the melting point of potassium alum in the CRC Handbook. It is an inorganic salt, also called potassium aluminum sulfate with a formula of AlK (SO4)2 that is predominantly produced in the dodecahydrate form (AlK (SO4)2 * 12H2O). Aluminum beverage cans generally have a thin coating of plastic on the inside that protects the aluminum from the corrosive action of the chemicals in the beverage. Mubychem Group has several manufacturing facilities . It is also known as dodecahydrate form of potash alum. Aluminium dissolves as potassium aluminate,KAl (OH)4, salt.
