Questions asked by users might not always be phrased in the clearest way.
Can HCl and add NaCl ( 0.5 molar nacl) at PH3 dissolve Al2o3 in room temperature?
Accepted Answer
Al2O3 is amphoteric, meaning it can react with both acids and bases. HCl is an acid, and while it can dissolve Al2O3, the presence of NaCl will not significantly enhance this reaction. The pH 3 environment indicates an acidic solution, which will favor the dissolution of Al2O3. However, the solubility of Al2O3 in HCl is influenced by factors like temperature, concentration, and the presence of other ions. For optimal dissolution, higher temperatures and greater HCl concentrations are generally recommended.
