The pH scale ranges from 0 to 14, with a pH of 7 being neutral. Buffers are solutions that moderate pH changes when an acid or base is added to the buffer system. Buffers are important in biological systems because of their ability to maintain constant pH conditions.
Figure 1: Water spontaneously dissociates into a proton and hydroxyl group. The proton will combine with a water molecule forming a hydronium ion. The pH of a solution is a measure of the concentration of hydrogen ions in a solution (or the number of hydronium ions).
Approximately 60–70 percent of the human body is made up of water. Without it, life as we know it simply would not exist. The polarity of the water molecule and its resulting hydrogen bonding make water a unique substance with special properties that are intimately tied to the processes of life.
30 lip 2022 · The pH scale, which measures from 0 to 14, provides an indication of just how acidic or basic a substance is. Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale).
