What is the pH of healthy drinking water, what are the alkaline drinking waters?

You should drink natural weak alkaline water, pH = 7 is theoretically neutral, so it should be close to 7 between 7 and 8 to be called weak alkaline water.

Alkaline drinks include: sports drinks, mineral water, soda, fruit juice drinks, green tea, etc.

Ordinary water is generally pH equal to 7, which is neutral, and ordinary water is separated into oxidized water and reduced water according to the principle of electrolysis, and acidic water (pH<7) and alkaline water (pH>7) are obtained respectively. Generally speaking, the alkaline water we talk about in daily life is weakly alkaline water, and some people call it "soda water".

At present, the alkaline water on the market can be divided into two categories, one is the alkaline water made by the alkaline water dispenser equipment (mostly for families), and the other is the alkaline water products made by bottled drinking water enterprises (mostly bottled mineral water).

1. Soda: The soda that we can often drink in ordinary life is a good alkaline drink, and the alkalinity of the soda itself is weakly alkaline.

2. Apple cider vinegar drink: The apple cider vinegar drink that is often drunk in daily life is also an alkaline drink, and the content of some nutrients contained in the apple cider vinegar drink is also extremely rich.

3. Natural mineral water: The natural mineral water that we can often eat in life is a very good alkaline drink, and the nature of natural mineral water is actually similar to that of soda in general life, which is a weakly alkaline drink, because some trace mineral elements contained in natural mineral water are extremely rich.

4. Green tea: Green tea is also an alkaline drink, because green tea itself contains various alkaline substances.

The pH of water is divided by the pH value of the water: acidic water with a pH value of <7; pH = 7 is neutral water; Between the pH values are weak alkaline water; A pH above is strong alkaline water and should be drunk under the guidance of a doctor.

Hello dear! Some substances are sold on the market to regulate the pH of water quality. For example, there are four main types of pH adjustment stones.

You can choose a specific pH adjustment stone to adjust the pH of water according to the specific requirements of the aquarium fish for the pH of the water quality. After selecting the right adjustment stone, you can directly put it near the filter tank or water outlet to adjust and stabilize the pH value of the water quality in the aquarium. Secondly, you can also choose sparkling water to adjust the pH of the water quality.

Generally speaking, phosphoric acid soda can reduce the pH value of water quality; Bicarbonated soda, which can increase the pH of water quality. There is also a pH increase and decrease agent on the market, which is mainly divided into powder and liquid. Also according to the specific changes in the pH of the aquarium, the appropriate dosage is selected to adjust the pH value of the water quality.

Generally speaking, increasing the modulation dose can increase the pH value, and decreasing the dosage can effectively reduce the pH value.

Normal pure water, the pH value should be, drinking water refers to water that can be directly supplied to the human body for drinking without treatment. Water is the main component of body fluids and is an important substance that makes up cells, tissue fluids, plasma, etc. As the medium of all chemical reactions in the body, water is the platform for the transportation of various nutrients and substances.

The hardness of water refers to the content of salts dissolved in water, that is, the content of calcium salts and magnesium salts, and the unit of hardness is ppm, and 1ppm represents the calcium carbonate content in water 1 milligram liter (mg l).

Water below 142 is called soft water, water above 285 ppm is called hard water, and water between 142 285 is called moderate hard water. Rain and snow water are soft water, and river water, river water, and lake water belong to moderately hard water; Spring water, deep well water, and seawater are all hard water.

The pH of water has no effect on the health of the body, and there is no need to worry about the pH of drinking water.

In the human body, there is a very complete metabolic system, which can regulate the acid-base in both directions, so that the pH value of different parts of the body is always stable. The various types of water sold on the market are indeed acidic and alkaline due to different water sources and different mineral contents.

However, the "acidity and alkalinity" of food itself and its "acidity and alkalinity" ("acidity and alkalinity" is the acidity and alkalinity of the products formed by metabolism after digestion and absorption by the human body) are sometimes even opposite, for example, lemons are weakly acidic fruits, but the products formed after eating are weakly alkaline. Whether you drink weakly alkaline water, ordinary mineral water, cool boiled water, etc., it will not change the pH value of the human body.

Abstract:Introduction to drinking water knowledge-characteristics-classification: The acidity and alkalinity of Qi Feng's drinking water are chemically expressed by pH value, pH=7 is neutral, pH<7 is acidic, and pH>7 is alkaline.

The pH of drinking water is better.

The acidity and alkalinity of drinking water are chemically expressed in terms of pH value, with pH=7 being neutral, pH<7 being acidic, and pH>7 being alkaline.

1. PH index in water quality standards.

1.World Health Organization Drinking Water Quality Standards: No specific indicators. It shows that low pH has corrosive effect; High pH affects the sense of taste, with a soapy taste; To make chlorination more effective, pH 8 is preferable.

2.U.S. EPA (Environmental Protection Agency) drinking water quality standards: first-class water, there are no specific standards for high branches; Level 2 water,.

3.European Union (EC) Drinking Water Quality Standards: For bottled or bottled water, the pH minimum is reduced to 4-5.

4.Japanese Drinking Water Quality Standards:

5.China's GB5749 Sanitary Standard for Drinking Water:; GB17324 bottled purified drinking water:. These indicators are in line with those of developed countries.

Water that meets the standards can be drunk with confidence, and there is no question of whether it is better to drink alkaline or acidic water.

Second, a lot of natural good water is acidic.

Danquan, Daming Mountain, Wuming County, Guangxi: PH is; Zhejiang Hangzhou Hupao Spring:. However, some natural waters, such as Taihu Lake water and tap water made from it, are not of good quality.

Therefore, it is not scientific to classify water quality by acidic or alkaline, but should be determined by whether it meets water quality standards, impurities in the water and its pollution.

3. Water is drunk into the stomach, and the environment of the stomach is acidic, with a pH of 2-3

1.Gastric juice function: (1) sterilization; (2) Aid digestion.

2.Gastric juice is a more acidic buffer solution. No matter what water you drink, when you drink it in your stomach, the pH level changes to acidic.

Fourth, the "acidity and alkalinity" of food itself and its "acidity and alkalinity" (formed by metabolism in the human body after digestion and absorption after eating) are two different things, and sometimes even opposite.

1.Most meat (pig, beef, chicken, duck, fish, shrimp, crab and other animal meats) and cereals (rice, flour, peanuts, etc.) are "acidgenic" foods.

2.Most vegetables (such as greens, turnips, onions, spinach, etc.), fruits (apples, bananas, oranges, strawberries, etc.), fungi (mushrooms, etc.), algae, etc., are "alkaline" foods.

3.Water is neither acidic nor alkaline-causing food.

4.The yolk of an egg is acidic, while the egg white is an alkaline food.

5.Most vegetables, fruits, etc. are acidic, but they are also "alkaline" foods.

Therefore, eating "alkaline" foods and drinking alkaline water are completely different things. The so-called statement that "only drinking alkaline water is good, and drinking weakly acidic water is harmful" has no scientific basis and is misleading propaganda. As long as the drinking water meets the hygienic standards, whether it is weak acid or weak alkaline band, it can be drunk with confidence.

The pH of drinking water is generally considered to be in the slightly acidic to neutral range. In general, pH is considered to be in the safe and appropriate range.

Drinking water that is too acidic or too alkaline may have some health effects. Excessively acidic water may have a corrosive effect on teeth and oral health, while excessively alkaline water may alter the acid-base balance of the gastrointestinal tract.

It is important to note that the pH value is only an indicator of the quality of drinking water, and the quality of drinking water depends on several factors, including trace elements, heavy metals, bacteria, viruses, etc. When choosing drinking water, it's best to choose drinking water that has been safely treated and tested to ensure healthy and safe water quality.

If you have concerns about the water quality you are using or purchasing, it is advisable to contact your local water quality testing agency or the relevant health department for more detailed and accurate information.

In general, the ideal pH of drinking water is between to. The water brother limbs in this range are considered neutral or slightly alkaline and have no negative impact on the physical health of most people and are able to meet daily needs.

However, it should be noted that the pH value is only an indicator of the acidity and alkalinity of the water, and healthy drinking water should also meet other water quality standards, such as safety limits for microorganisms, chemicals and heavy metals. Therefore, the quality of drinking water depends not only on its pH, but also on other factors related to the world.

If you have questions about the pH of your drinking water, it is advisable to have a water quality test or consult your local water authority or professional body to ensure that your drinking water meets safe and healthy standards.

The pH of drinking water has an impact on human health, but there is no one definitive optimal pH. In general, water with a neutral pH of 7 is the best choice for most people. This is because the pH of the body's blood and cell fluids is also close to neutral and is maintained in between.

Water that is too acidic or too alkaline may have a negative impact on human health. Overly acidic water may cause an increase in stomach acid, causing stomach upset or digestive problems. Overly alkaline water may interfere with the normal secretion of stomach acid, affecting the digestion and absorption of food.

However, it is important to note that the body's tolerance to pH varies from individual to individual. Some people with celery may be more sensitive to acidic or alkaline water, while others may be more tolerant. Therefore, it is important to choose the pH of drinking water that suits you.

In general, maintaining a neutral pH of drinking water is a safer and more appropriate option. If you have any questions or special needs about the pH of your drinking water, it is recommended to consult a medical professional or dietitian.
