Scientists Say: pH | Science News Explores A base adds negatively charged ions called hydroxides (OH-). The pH scale runs from zero to 14. A low pH, close to zero, is very acidic, with many free H+ ions. Lemon juice, with a pH of around two, is a good example. A high pH, close to 14, is very basic, with many free OH-ions. Basic solutions are as known as alkaline. The pH Scale | Biology for Non-Majors I | | Course Hero 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). If foreign strong substances dramatically change this pH, our bodies can no longer function properly.

Ph scale label. Acids, Bases, & the pH Scale - Science Buddies Each one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. The pH scale is theoretically open-ended but most pH values are in the range from 0 to 14. It's a lot easier to use a logarithmic scale instead of always having to write down all those zeros! The pH Scale | Biology for Majors I - Lumen Learning The pH scale is, as previously mentioned, an inverse logarithm and ranges from 0 to 14 (Figure 1). Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline. Extremes in pH in either direction from 7.0 are usually considered inhospitable to life.
