To explain the acid-alkaline balance we have to quickly visit at a
little chemistry :-)
Here is a brief introduction:
*The pH scale, that you may remember from high school, indicates the
acidity of a solution.
* Alkaline solutions have pH>7 and acidic solutions pH<7
*The pH is associated with hydrogen concentrations in a solution.
*Acidic solutions have a high concentration of H+ and alkaline have a
low concentration of H+.
*Acidity affects the chemical reactions in the body. Normally the blood
has a pH of about 7.4 and is slightly alkaline. If the value falls or rises
beyond the limits, the condition can be serious.
*The pH in the blood is used as a measure of acidity in the body.
*The pH is different on different places inside the body. The digestive
juice from the pancreas has the highest pH, around 8, and stomach acid has the
lowest at around 2-3. Distilled water has a pH of 7, which is considered
neutral.
*Since the pH scale is logarithmic, each pH unit indicates a change of
ten times the H+ concentration.
