An Example of a pH scale is located above. A pH scale ranges from 1-14, 1 being the most acidic and 14 being the most basic. An acidic pH has a value below 7, a basic pH is greater than 7, and a pH of 7 is considered neutral (ex: water). Some common acidic functional groups are alcohols (OH) and carboxylic acids (COOH). Some basic functional groups are amines (NH3) and ethers (CH2OCH2).

You can predict if an amino acid will be acidic or basic according to its structure. For example, <scene name='Tutorial:Basic_Chemistry_Topics/Glu/1'>glutamic acid</scene> contains a carboxylic acid functional group, which was stated previously to be an acidic functional group that lowers the pH of the amino acid. On the other hand, arginine is classified as a basic amino acid. The functional group of arginine contains a guanidine group. A guanidine group contains amine groups, increasing the pH of the amino acid.
