Base (chemistry) - Wikipedia, The Free Encyclopedia
One advantage of this low solubility is that "many antacids were suspensions of metal hydroxides such as aluminum hydroxide and magnesium hydroxide." In this process, the water molecule combines with a strong base, due to the water's amphoteric ability; and, a hydroxide ion is released. ... Read Article

Amphoteric “Al ” By: Dr. Prem D A metal hydroxide acts basic but a non-metal hydroxide acts acidic. (Aluminum is next to the semimetal Si (OH) 3] it is covalent. Al(OH) 3 is mostly polar covalent. This is likely to break at 2 different places, explaining the amphoteric behavior. δ ... Document Viewer
