Aunt Alexandra is a very prejudice woman. She does not tolerate Calpurnia being the only motherly figure for scout. She shows Calpurnia little respect because she believes Cal â¦ is of lower class. She also judges others because of their family name.

Acids on the other hand would contribute #H^+# ions when dissociated. The easiest way to identify Arrhenius bases is to identify #OH^-# in a compound formula.
The Arrhenius theory is simple and useful. It explains many properties and reactions of acids and bases. For instance, mixing hydrochloric acid (HCl) with sodium hydroxide (NaOH) results in a neutral solution containing table salt (NaCl). However, the Arrhenius theory is not without flaws.There are many well known bases, such as ammonia (NH 3) that do not contain the hydroxide ion. Furthermore, acid-base reactions are observed in solutions that do not contain water. To resolve these problems, there is a more advanced acid-base theory.ewis acids and bases react to create an adduct, a compound in which the acid and base have bonded by sharing the electron pair. Lewis acid/base reactions are different from redox reactions because there is no change in oxidation state.
