What is a pH?
This term indicates the values of a solution. There are numerous solutions and elements in which you can test them and at the same time, there are different meanings of each claimed value. Even in the human body, there are different pH, for instance about the blood, the urine or the skin.

There are three types of pH: neutral, acidic or alkaline.
In better words, pH is the index of the degree of acidity or basicity or neutrality of a solution. In terms of numers it can be between 0 and 14. The scale of values ​​begins on the degree of maximum acidity 0 (strong acid) and ends with 14, that of greater basicity (strong base).

Accordingly, this means that neutrality is present in the middle of the scale of values.

So, all the values ​​less than 7 indicate a pH progressively more acid, while those more than 7 indicates an alkaline pH.
