There are two types of acid/bases: 1) Brønsted acid/bases; 2) Lewis acid/bases.
1) Brønsted definitions of acids and bases:
• An acid is a species having a tendency to lose a proton
• A base is a species having a tendency to accept a proton
Example: CH3COOH + NH3 “leftrightarrow” NH4+ + CH3COO–
Here CH3COOH is an acid, NH3 is a base; and NH4+ is an acid, CH3COO– is a base.
2) Lewis definitions of acids and bases:
• Acids are electron pair acceptors.
• Bases are electron pair donors.
