pH (potential Hydrogen)

What Is Hydrogen

Hydrogen (H) is the lightest and simplest element.  A Hydrogen atom is made up of one proton and one electron.  At room temperature, Hydrogen is gas - as it cools it becomes liquid.  Hydrogen is one of 9 essential macronutrients and is a major component of organic molecules.  Hydrogen supplies building blocks of all organisms whether plant, animal or human.  Each water molecule contains two Hydrogen molecules and one Oxygen molecules (H20).
pH Definition
In chemistry, the degrees of acidity or alkalinity of a substance are expressed in pH values.  The neutral point, where a solution would be neither acid nor alkaline is pH 7.  Increasing acidity is expressed as a number less than 7, and increasing alkalinity is a number great than 7.  Maximum acidity is pH 0 and maximum alkalinity is pH 14.  Because each unit on the scale represents a logarithm, there is 10-fold difference between each unit (pH 5 is 10 times as acid as pH 6 and pH 4 is 100 times as acid as pH 6.  Expressed mathematically, pH is logarithm of the hydrogen ion concentration divided into one - Log 1/H+

An acid is a substance that releases hydrogen into a solution.   An alkaline substance is one that removes hydrogen from a solution. 

pH is a critical measurement. Life depends upon it. For instance, human blood is basic with a pH between 7.3 and 7.5. If the pH of blood drops below 7.3, acidosis occurs. If the blood pH rises above 7.5, alkalosis occurs. Our human existence depends upon a balanced and buffered blood pH.

Most body functions occur at only certain levels of acidity or alkalinity, as well as, many enzymes and chemical reactions work best at a specific pH.  A minute change in pH can have a profound effect on body function.

Ideal pH Values
When pH = 8:  There are 6 billion H+ ions in solution
When pH = 7:  There are 60 billion H+ ions in solution
When pH = 6:  There is 600 billion H+ ions in solution
