| | Aluminium Potassium Sulphate Dodecahydrate Usage And Synthesis |
| Description |
Aluminium Potassium Sulphate Dodecahydrate (alum) is a naturally occurring mineral that has been used in a multitude of applications from printing to electrolytic copper plating.
| | Physical properties | Aluminium Potassium Sulphate Dodecahydrate is a white odorless solid, soluble in water.
| | Uses |
Hydrolysis of the Aluminium Potassium Sulphate Dodecahydrate yields aluminum hydroxide as a precipitant. Industrial uses include paper sizing, water purification, and textile dyeing (mordant). It is also used in pickling, baking powder, fire extinguishers, and astringents.
| | Definition | Aluminum potassium sulfate dodecahydrate is an inorganic sulfate salt of aluminum and potassium.Potassium aluminium sulfate dodecahydrate is a hydrate resulting from the the formal combination of anhydrous potassium aluminium sulfate with 12 mol eq. of water.
| | Effects | Aluminium Potassium Sulphate Dodecahydrate has a role as an astringent, a flame retardant and a mordant.
| | Solubility in organics | Soluble in glycerol. Insoluble in alcohol.
