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). | An Example of a pH scale is located above.

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, <scene name='Tutorial:Basic_Chemistry_Topics/Arg/1'>arginine</scene> is classified as a basic amino acid. The functional group of arginine contains a guanidine group. A guanidine group contains amine groups, which increase the pH of the amino acid. | You can predict if an amino acid will be acidic or basic according to its structure.
