Aluminium (III) phosphate, is an inorganic salt discovered in part minerals and also used through the chemical as catalyst and also by the pharmaceutical market to attain chemotherapeutics drugs.
You are watching: What is the formula for aluminum phosphate?
Formula and also structure: The aluminium phosphate chemistry formula is AlPO4 and also its molar mass is 121.9529 g mol-1. Aluminium phosphate mainly exists in nature as the anhydrous salt AlPO4. The dihydrate and pentahydrate forms likewise exist in nature: AlPO4.2H2O and also AlPO4.5H2O. The molecule is created by the phosphate an anion PO43- and also the aluminium cation Al3+. The anhydrous salt framework is very similar to other minerals as quartz, v an trigonal crystal system, yet the dihydrate type is similar to NaCl structure and 6 cations coordinated to 6 anions and viceversa. Its chemistry structure can be composed as below, in the common representations provided for organic molecules.
Occurrence: Aluminium phosphate is found in nature, an in similar way to various other aluminium salt, is a mineral: the berlinite. The dihydrate kind is discovered in the minerals: variscite and also meta-variscite. The significant reserves of this minerals are in Australia and Southern Africa.
Preparation: Aluminium phosphate is extracted from the minerals berlinite, variscite and meta-variscite. Chemical approaches to prepare it space not very extended or connected in literature.
Physical properties: Aluminium phosphate is an odorless, white crystalline powder. Its density is 2.567 g mL-1. The melting allude is 1800 ºC and above this temperature, aluminium phosphate decomposes. The is insoluble in water however slightly dissolve in hydrochloric acid and nitric acid.
Chemical properties: Aluminium phosphate go not have only the framework of quartz SiO4, the has additionally the chemical properties that it. Aluminium phosphate gift piezoelectric properties. Moreover, aluminium phosphate exhibits chirality, an characteristic an extremely common in necessary compound yet so rare in not natural salts.
Uses: Aluminium phosphate is supplies in electrical and electronic sectors due the properties together piezoelectric material. That is additionally used in the production of rubbers and adhesive. Aluminium phosphate is a ingredient of the many used antiacids.
