What are Acid and Alkaline?
Water (H2O) ionizes into hydrogen (H+) and hydroxyl (OH-) ions. When these ions are in equal proportions, the pH is a neutral 7. When there are more H+ ions than OH- ions then the water is said to be acid. If OH- ions outnumber the H+ ions then the water is alkaline. The pH scale goes from 0 to 14 and is logarithmic, which means that each step is ten times the previous. In other words, a pH of 4.5 is 10 times more acid than 5.5, 100 times more acid than 6.5 and 1,000 times more acid than 7.5. Acid and Alkaline Minerals and Foods Minerals with a negative electrical charge are attracted to the H+ ion. These are called acid minerals. Acid minerals include: chlorine (Cl-), sulfur (S-), phosphorus (P-), and they form hydrochloric acid (HCl), sulfuric acid (H2SO4), and phosphoric acid (H3PO4). Minerals with a positive electrical charge are attracted to the negatively charged OH- ion. These are called alkaline minerals. Nutritionally important alkaline minerals include calcium (Ca+), potassiu
