Acids "donate" #H^(+)# when they react. Some conjugate bases are stronger than others, meaning they attack or attach to hydrogen ions with varying strengths. We can show the relationship between an acid and its conjugate base using this expression: HA --> H+ + A-, where HA is the acid, H+ is the hydrogen ion, and A- is the conjugate base of the acid. Since it can act as an acid in presence of a strong base than it such as NH 3 and act as a base in presence of strong acid such as HCl. The following are examples of acids and their corresponding conjugate bases: A conjugate base can be easily identified, since it is basically the acid minus its protons HA ----> A-.
