Scientists use something called a pH scale
to measure how acidic or basic a substance is.
Advanced Hydration Technology alkaline drinking water is slightly alkaline on the pH scale
While they can understand the pH scale
, interpreting its association with hydrogen ion concentration is confusing.
To avoid using such awkward and cumbersome numbers, the Danish biochemist Soren Sorensen devised the pH scale
and introduced the pH definition.
Enzymedica, whose information is similar to many other sites on urine pH, says: "The optimal urine pH is between 6 and 7 on the pH scale
The acidic quality of the water has also improved, after previous tests showed it measured 2 on the pH scale
In fact, Drano is at the opposite end of the pH scale
in that the active ingredient is sodium hydroxide (NaOH), more commonly known as lye.
In this sense, beverages are a good application for natural colors because beverages tend to be on the lower pH scale
For comparison, on the logarithmic pH scale
