What is pH scale?

PH scale is used to rank solutions in terms of acidity or basicity (Ex. alkalinity).

Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H+ start superscript, plus, end superscript ion concentration.

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.

The pH inside human cells (6.8) and the pH of blood (7.4) are both very close to neutral. Extreme pH values, either above or below 7.0, are usually considered unfavorable for life. However, the environment inside your stomach is highly acidic, with a pH of 1 to 2.

 How does the stomach get around this problem? The answer: disposable cells! Stomach cells, particularly those that come in direct contact with stomach acid and food, are constantly dying and being replaced by new ones.

“The lining of the human stomach is completely replaced about every seven to ten day’s”.
