(potash)alum
Molecular formula :
MW :
CAS :

nature : K2 (SO4) 2 Al2 (SO4) 3 24H2O or Kal (SO4) 2 12H2O also known as potassium aluminum sulfate, potassium sulfate and potassium alum. The crystal water containing potassium sulfate and aluminum sulfate salt. Colorless octahedral crystals. A county flavor. Density 1.75. 92 ° C melting point. Dissolved in water, with hydrolysis generated colloidal aluminum hydroxide precipitation. When heated water lost from a white crystalline powder (siu alum). For purifying agent and Mordant and baking powder used in the system, such as potassium and ammonium sulphate. May alum stone scriptures calcined, extraction, crystallization and prepared.
