Al(OH)3 + NaOH. Virtually all the aluminium hydroxide used commercially is manufactured by the Bayer process[10] which involves dissolving bauxite in sodium hydroxide at temperatures up to 270 °C (518 °F). Al + H2O → (6). The waste solid, bauxite tailings, is removed and aluminium hydroxide is precipitated from the remaining solution of sodium aluminate. Please register to post comments. The unbalanced equation is NaCl(aq) + H2O(ℓ) → NaOH(aq) + Cl2(g) + H2(g). Heating converts it to activated aluminas, which are used as desiccants, adsorbent in gas purification, and catalyst supports. Fatima Farrell. The aluminium salt, when ingested, binds to phosphate in the intestines and reduce the amount of phosphorus that can be absorbed. However, it has little capacity to stimulate cellular (Th1) immune responses, important for protection against many pathogens,[27] nor is it useful when the antigen is peptide-based. using water-miscible non-aqueous solvents like ethanol) to form an amorphous aluminium hydroxide powder, which is readily soluble in acids. Alfred Errol. It is selected for these applications because it is colorless (like most polymers), inexpensive, and has good fire retardant properties. You can use parenthesis () or brackets []. 1 decade ago. Nonetheless, both gibbsite and hydrargillite refer to the same polymorphism of aluminium hydroxide, with gibbsite used most commonly in the United States and hydrargillite used more often in Europe. [22], This compound is also used to control hyperphosphatemia (elevated phosphate, or phosphorus, levels in the blood) in people and animals suffering from kidney failure. 7:22.
