REACTIONS OF ACIDS AND BASES . Characteristics of ACIDS Important to Know. All bases contain OH-.All acids contain H+: H+ (aq) +OH-(aq) ÆH2O(l) •The problem with this theory is that it requires that base have an OH-group. Acids versus bases 1. 0000010870 00000 n 0000050213 00000 n While a Lewis base is a substance that can a pair of to form a covalent bond. An acid and base are not two totally separate chemicals but are related. Acids and bases share some properties but are different in others. Classify each of the following as an acid or a base. acids are added to water, let’s consider the dissolving of gaseous hydrogen chloride, HCl(g), in water. Bases often have a bitter taste and are found in foods less frequently than acids. 0000025974 00000 n Knowing what you know about naming acids, name six different acids and four different bases. All Bronsted-Lowry acids and bases are also Lewis acids and bases, but not necessarily the other way around.
