Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al2O3), the latter of which is also amphoteric. Th…

One way of controlling cadmium in effluent streams is to add sodium hydroxide, which precipitates insoluble Cd(OH) 2 (K s = 2.5E–14). WebIn the molten hydroxide, La (CH 3 COO) 3 reacts with NaOH/KOH to produce crystalline La (OH) 3 nuclei, which then grow along the direction to form nanobelts. In this growth mechanism, disperse single-crystalline nanostructures can also be obtained in the absence of any surface-capping materials.
