Aluminium Hydroxide Extra Pure
Original price was: $ 19.00.$ 18.97Current price is: $ 18.97.
Aluminium Hydroxide Extra Pure is a high-purity, white, odorless, and amorphous powder widely used in laboratory research and analytical applications. As an amphoteric compound, it reacts with both acids and bases, making it ideal for studying neutralization reactions, buffer systems, and solubility equilibria. In inorganic and coordination chemistry, it serves as a precursor for various aluminum compounds and plays a role in ion exchange and adsorption studies. Its extra pure grade ensures low interference in sensitive analytical procedures such as gravimetric analysis. Due to its tendency to absorb carbon dioxide from the air, it should be stored in tightly sealed containers under dry conditions to maintain its chemical integrity and performance in laboratory environments.
