What is PH level? How is the pH formula, what is the pH determined for, some methods of determining the pH and pH of today’s popular solutions and especially the effects of pH in life, signs of low pH, how to correct when PH is too low. That is all the question surrounding the term PH?

In the notes on product packaging or in chemistry textbooks, we have certainly seen the words pH or pH. And we simply understand that pH is a scale used to measure the Acidity or Base of a substance, telling us whether the water is alkaline or not. All insights stop there while pH can bring much more about these insights. Therefore, today Trung Son Company will explore with you all the information about pH so that you have a better overview of it. To make it easier, we will go from the simplest, which is the concept of pH and what is pH?

pH scale


The pH is understood as the activity level of H+ ions in the solution environment under the influence of an electrolyte constant. All solutions that exist in liquid form have a specific pH, and pH affects that liquid for good or for harm.

Viewing: what is ph

pH is defined as the negative logarithm of the hydrogen ion concentration running from 0 to 14. It is mathematically expressed as:

The formula for calculating pH: pH = -log In the laboratory or in studies, almost all processes in which water is present require a pH measurement. This includes chemical diagnostics, environmental science water quality testing, and biological environmental experiments.

All living organisms depend on an appropriate pH level to sustain life. All people and animals rely on internal mechanisms to maintain a certain pH level. So what is Ph?


? The pH is used to distinguish between different types of solutions or the characteristics of each type of solution. By convention, the pH of water is the most standard value = 7. Solutions with a pH of 7 are basic (alkaline) solutions.
