Jan 20, 2010 · A small drop in pH means big change in acidity: The pH of seawater is near 8, which makes it mildly alkaline, or basic; but any decrease in the pH of a liquid is considered “acidification.” The key danger factor is an increase in dissolved hydrogen ions.(Woods Hole Oceanographic Institution)
For example, in humans, arterial blood pH normally falls within the range 7.35–7.45. A drop of 0.1 pH units in human blood pH can result in rather profound health consequences, including seizures, heart arrhythmia, or even coma (a process called acidosis ).
However, there is another layer that requires calculus: related rates pertaining to pH change. The concepts of related rates taught in calculus classes can be expanded to pH as a solution evaporates, is diluted, or is titrated. This article explores problem-solving in this specific context.
1 day ago · The human body is great at regulating acids and bases to keep a stable pH balance at around 7.4—a slightly alkaline value—through organs like the kidneys and lungs. Some proponents of the alkaline diet say that acid-forming foods, like meat, eggs, and grains, can throw off the body’s pH balance and cause a variety of health problems. To ...
The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
