Unformatted text preview: hydrogen). NOTE: pH = the negative log of H + in the substance so that on the pH scale: 1 = maximum H + , or the most acid. 14 = the most basic 7 = neutral (which is the pH of pure water) N ow, why do we care? Reactions of living organisms are very sensitive to levels of pH. It is therefore critical to maintain proper pH in an environment where cells and tissues are exposed to much variation in H + concentration....
