The PH value of drinking water is 6.5-8.5. It is best to determine the most direct environmental protection and health for the people according to the Hygienic Standard for Drinking Water enforced in earlier years. The pH value of drinking water should be between 6.5 and 8.5, and it should be marked on the bottle. Scope applies to pure water, mineral water, etc. According to the regulations, the pH value of drinking water should be 6.5-8.5.
Extended data:
Acidity and alkalinity of drinking water:
1, mineral water and mountain spring are weakly alkaline water. For water, whether it contains minerals and trace elements is the key to determine its acidity and alkalinity. Water in nature, such as spring water and lake water, is generally weakly alkaline water, because nature endows it with rich minerals and trace elements, which will be made into mineral water and mountain spring water that we often see in the market.
2. Pure water is acidic water. Pure water, as its name implies, contains nothing but water molecules, and water is naturally acidic.
Mineral water is more sour than pure water. The so-called mineral water is an artificial mineral water that is popular in the market now. Because minerals are artificially added, the acid-base balance of water is destroyed, and it is even more acidic than pure water.
