Summary
This lecture defines pH as the negative logarithm of hydrogen ion concentration. It's a crucial concept in chemistry and biology, with a scale ranging from 0 to 14. Neutral solutions have a pH of 7, acidic solutions have a pH less than 7, and basic solutions have a pH greater than 7.

Definition of pH It is the negative logarithm of hydrogen ion concentration (- log H+). It refers to the concentration of hydrogen ions in a solution. The term, widely used in chemistry, and biology, translates the values of the concentration of the hydrogen ion which ranges from 0–14. A neutral solution has a pH of 7, an acidic solution has a pH < 7, and a basic solution has a pH >7.
