qu'est-ce que le pH ?

je vous préviens, je suis partie dans Alkalize or Die de Theodore A. Baroody, vous aller donc en entendre parler!

depuis le temps que je me demandais ce que c'était dans les fait que le pH!!!

Whether a substance is alkaline or acid is determined by its pH (potential Hydrogen), which measures the number of hydroxyl (OH-) ions which are negative and alkaline-forming as opposed to the amount of hydrogen (H+) ions that are positive and acid-forming.
From the standpoint of pure energy, pH is the measurement of electrical resistance between negative and positive ions in the body. In other words, pH measures how much the negative ions (alkaline-forming) and positive ions (acid-forming) push against one another.
