Several antacids have aluminum hydroxide, Al(OH)3, as an active ingredient. How can we prove that the supernatural or paranormal doesn't exist? The lining of the esophagus is not protected from the corrosive effects of stomach acid the way the lining of the stomach is, and the results can be very painful. Calcium chloride is the salt of hydrochloric acid and calcium hydroxide. Note that HNO2 is a weak acid and NH4OH actually is NH3 + H2O (a weak base); therefore, the decision rests upon which is stronger, the weak acid or the weak base.

If you consider the species in this chemical reaction, two sets of similar species exist on both sides. Here are examples of the four types. The OH functional group gives the properties of the Lewis base, and hence CH3OH has properties of both weak acid and bases. I suggest you write them even though you think neither anion nor cation is hydrolyzed. Such compounds are also called amphoteric compounds as it exhibits properties of both acids and bases. Since both the acid and base are strong, the salt produced would be neutral.
