Popular Science: Explanation on mineral salt precipitation caused by drinking natural mineral water

Drinking natural mineral water is pure natural mineral water. In addition to containing metasilicic acid, it also contains a variety of minerals and trace elements such as calcium, magnesium, sodium, and potassium that are beneficial to the human body. The source of drinking natural mineral water is groundwater, with a constant temperature of 25°C. The processing process is extremely simple. Only simple physical filtration is performed, and no other substances are added. Before filling, the mineral salt composition in the water maintains the ionic state during underground storage. After filling into the bottle or barrel, the surrounding environment during transportation, storage and storage is different from the original underground environment, especially the temperature changes are obvious, the ion price changes, which leads to the precipitation of a small amount of mineral salt crystals, making the bottle drinkable Precipitation of mineral salts in the natural mineral water is visible to the naked eye. GB8537-2008 "Drinking natural mineral water" standard for sensory requirements: "Allows a very small amount of natural mineral salt precipitation, but must not contain other foreign objects." This feature is also the fundamental difference between drinking natural mineral water and other commercially available pure water, distilled water and other water species. These drinking water species contain little or no natural mineral salts, so there will be no crystallization of mineral salts. Phenomenon.
