How do you know water is acidity or alkalinity?

Published by admin July 13,2020

We often hear the words, acidic water, alkaline water. The acidic, alkaline refers to the PH value  (pondus hydrogenii value), generally speaking, natural water PH value generally between 6.5 and 8.5. PH value has important meaning to purifying treatment, alkaline water has the effect of precipitation, but the effect of chlorination disinfection and sterilization is reduced, acidic water has erosion effect, easy to corrode the pipeline, affected the water quality.

Sometimes we can hear the phrase, "water is really hard," "water is really soft," and the term hard soft refers to the hardness of the water, which refers to the total concentration of calcium and magnesium ions in the water, including carbonate hardness and non-carbonate hardness.The PH value indicates the strength of an aqueous solution.The aqueous solution of pH,  pH=7was neutral; acidic water of PH,  pH <7; and alkaline water of pH, pH >7 .Water in the south is mostly acidic, while water in the north is mostly alkaline. So is acidic water good for you, or is alkaline water good for you?

In fact, the human body's digestion and absorption process is a very complex process.After the person drinks water, water first arrives in the stomach, the environment of the stomach is acidity, pH value is about 1 ~ 2, belong to strong acidity.Gastric juice is a kind of buffer solution with strong acidity, no matter what water you drink, after drinking into the stomach, the pH value will change, will become acidic water, only in this way, gastric juice can kill bacteria, can help digestion.

PH value

You don't know that, do you?In fact, most good natural water is acidic. The country with the longest life expectancy in the world is Japan. In 1961, the water quality was analyzed of Japan's "longevity village", and the average pH value was 6.39, indicating that the water was acidic.

And human body falls in normal physiology condition, the pH value of blood should maintain accurately between 7.35-7.45.Once below 7.35, it can cause acidosis, dizziness, drowsiness, anxiety and even insanity.Higher than 7.45 also causes alkalosis, which can cause muscle cramps and heart problems.

We say acid water is good to the body or alkaline water is good to the body, only judging with this PH value, it is unscientific. As long as it meets the drinking standards, the water can be safely drunk
