The document covers fundamental concepts of chemistry relevant to biochemistry, including the structure of matter, types of chemical bonds, and various chemical reactions, particularly redox reactions. It also explains the significance of acids, bases, and pH in biological systems, detailing the pH scale and its implications for acidity and basicity. Overall, it emphasizes the importance of chemical principles in understanding biological processes.

42. pH
• In chemistry, pH also referred to as acidity or basicity, historically denotes "potential of hydrogen" (or "power of
hydrogen").
• It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions.
•
• A solution with a higher concentration of hydrogen ions than pure water is an acid, while a solution with a lower
concentration is a base.
• The pH scale is logarithmic and inversely indicates the activity of hydrogen ions in the solution.
• pH is measured on a scale of 0 to 14. On this scale, a pH value of 7 is neutral, which means it is neither acidic nor
basic. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more basic.
