Acid-base ph value of white vinegar
Acid-base ph value of white vinegar, acetic acid of white vinegar can kill staphylococcus, E. coli, S. cerevisiae, salinophilic bacteria in intestinal tract due to its strong bactericidal ability, help digestion and facilitate the absorption of nutrients in food, and the following is the acid-base ph value of white vinegar.
The acidity and alkalinity ph value of white vinegar1The ph value of white vinegar is around 2.4 according to the national standard. Nutritionally speaking, acid-alkaline food is to look at the acidity or alkalinity of the substances that go through metabolism and end up staying in the body, and it is true that there are a few foods that are the opposite of what is generally known.
Vinegar taste acid, but after metabolism, the anion will become water and carbon dioxide, carbon dioxide belongs to the acidic body through the lungs and exhaled out of the body, the remaining cations are mainly alkali metal ions, so vinegar belongs to the alkaline food. Although vinegar is classified as an alkaline food in nutritional science, it does not mean that vinegar has an effect on gastric acid reflux.
It is recommended that patients with acid reflux eat more steamed bread, bread, noodles, potatoes, baking soda and other foods. If this happens for a long time, it is best to go to the hospital to check if it is serious.
Selection of vinegar skills
1, look at the label. According to the requirements of national standards, vinegar products should be labeled with total acid content. The total acid content is a characteristic index of vinegar products, and the higher the content is, the more acidic the vinegar is.
2. Look at the color and body. Brewing vinegar with amber or reddish brown color and glossy is good. The quality of the product is better if the body is clarified, the concentration is appropriate, and there is no suspension and precipitation.
3. Smell aroma, taste. Good vinegar should have the unique aroma and ester aroma of vinegar, and there should be no bad odor. It has soft sourness, long aftertaste, mellow aroma, no astringency, and no peculiar odor.
The acidity and alkalinity of white vinegar ph value 2The ph value of vinegar is generally 2.9.
Acidity and alkalinity describes the degree of acidity and alkalinity of an aqueous solution, which is expressed by pH value. At the thermodynamic standard condition, an aqueous solution of pH=7 is neutral, while a pH7 one is alkaline.
pH less than 7 indicates that the concentration of H is greater than the concentration of OH, so the solution is more acidic, while pH greater than 7 indicates that the concentration of H is less than the concentration of OH, so the solution is more basic. So the smaller the pH, the more acidic the solution is; the larger the pH, the more basic the solution is.
In non-aqueous solutions or non-standard temperature and pressure conditions, pH = 7 may not mean that the solution is neutral, it is necessary to calculate the ionization constant of the solvent under such conditions to determine the value of pH for neutral. For example, at a temperature of 373 K (100 °C), the pH of a neutral solution is ≈ 6.
It is also important to note that the effective number of pH is recorded from the decimal point, and the portion before the decimal point is an exponent, which cannot be recorded as an effective number.
Normal: Newborn Immediately after birth 7.11-7.36 5-10 minutes 7.09-7.30 30 minutes 7.21-7.38 > 1 hour 7.26-7.49 1 day 7.29-7.45 Subsequently, 7.35-7.45 (H+ concentration 36-44 nmol/L)
