The most common feature of many acids is the presence of the hydrogen ion, H+.
Acid Identification
Concept #1: Binary Acids contain the hydrogen ion, H+, connected to an electronegative nonmetal that excludes oxygen.
Concept #2: Oxyacids contain the hydrogen ion, H+, connected to a polyatomic ion containing oxygen.
Example #1: Which of the following compound(s) cannot be classified as an acid?
a) H2Se b) HOCN c) HN3 d) C3H8 e) All are acids.
Ionic Salts
Concept #3: Cations can either be acidic or neutral depending on their identity.
Concept #4: Anions can either be basic or neutral depending on their identity.
Concept #5: Amphoteric Species can be either acidic or basic depending on their Ka or Kb values.
