Uses of Aluminum Hydroxide

Laboratory Uses of Aluminum Hydroxide

1. Precipitation Reactions:
   • Qualitative Analysis: Used to identify and separate metal ions in solution by precipitating insoluble hydroxides. Al3++3OH−→Al(OH)3text{Al}^{3+} + 3 text{OH}^- rightarrow text{Al(OH)}_3Al3++3OH−→Al(OH)3​
   • Purification: Employed to purify certain compounds by precipitating impurities as hydroxides.
2. Buffer Systems:
   • pH Control: Used to maintain or adjust the pH of solutions in various experiments due to its amphoteric nature (reacts with both acids and bases).
3. Adsorbent:
   • Chromatography: Occasionally used as an adsorbent material in chromatographic techniques for separating different compounds.
4. Reagent:
   • Synthesis: Acts as a starting material or reagent in the synthesis of other aluminum compounds, such as aluminum salts.
   • Aluminate Formation: Used in the formation of aluminates for various chemical syntheses. Al(OH)3+NaOH→NaAl(OH)4text{Al(OH)}_3 + text{NaOH} rightarrow text{NaAl(OH)}_4Al(OH)3​+NaOH→NaAl(OH)4​
5. Analytical Chemistry:
   • Gravimetric Analysis: Utilized in gravimetric methods to determine the concentration of aluminum ions in a sample by precipitating aluminum hydroxide and weighing the resultant precipitate.
6. Catalyst Support:
   • Catalysis: Sometimes used as a support material for catalysts in various chemical reactions due to its high surface area and chemical stability.
7. Adsorption Studies:
   • Environmental Chemistry: Employed in studies related to adsorption processes, such as the removal of contaminants from water.
