Q: Why is the vinegar?: Analysis of the chemical composition of vinegar, the main component is acetic acid, non-volatile acid, amino acids, sugar and so on. Therefore, vinegar disinfection and sterilization, reduce spicy taste, the protection of raw materials in the loss of vitamin C and other effects; also help digestion, improve the stomach acid environment, inhibit the propagation of harmful bacteria. So appropriate to eat vinegar for human health is good. But the first condition of the body's health is to keep the organ's normal work. When a large number of vinegar, a large number of vinegar into the body, will change the PH value of gastric juice to strengthen the acidity of the stomach, causing damage to the gastric mucosa. Healthy people a lot of vinegar can cause stomach pain, nausea, vomiting, and even lead to acute gastritis; and gastritis patients will make a lot of vinegar symptoms of stomach problems, ulcers can induce ulcers. At the same time, due to the large absorption of acetic acid will also affect the whole body's acid-base balance. This is because under normal circumstances, the human body blood, body fluid pH should be maintained between PH7.35-7.45, was weakly alkaline. Acid and alkaline food intake will affect the blood, body fluid pH. From the physiological point of view, acidic food intake too much, will cause blood, body fluids increased acidity, acidosis.

Q: What is called transition metal oxide doping: The so-called dopant oxide is doped with impurities in oxides, such as the incorporation of trivalent Al in ZnO, and the doping of oxides can affect and alter the original properties.

Q: What is inorganic salt: Inorganic salts are important for the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, and soft tissue contains more potassium. The inorganic salt ions in the body fluid regulate the permeability of the cell membrane, control the water, maintain normal osmotic pressure and acid-base balance, and help transport the general element to the body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiologic functions, which are constituents of enzymes that make up enzymes, hormones, vitamins, proteins and nucleic acids, or as activators of various enzyme systems. For example: to maintain the heart and brain activity, to help the formation of antibodies, play a useful role in the human body.

Q: Why are the tomatoes?: Not sour is sweet

Q: I will eat a boiled egg every morning, drink a box of milk before going to bed at night, to stop these things, eat only vegetables?: Strengthen exercise consumption.

Q: Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit: When the boron deficiency occurs, pollen tube germination is affected and poor fertilization leads to seed formation.

Q: What is the important character of Chinese made alkali?: (1) NH3 + H2O + CO2 = NH4HCO3 (2) NH4HCO3 + NaCl = NH4Cl + NaHCO3 ↓ (3) 2NaHCO3 (heating) = Na2CO3 + H2O + CO2 ↑ That is: ① NaCl (saturated) + NH3 + H2O + CO2 = NH4Cl + NaHCO3 ↓ ②2NaHCO3 = Heating = Na2CO3 + H2O + CO2 ↑ Ammonia reacts with water and carbon dioxide to form a molecule of ammonium bicarbonate, which is the first step. The second step is: ammonium bicarbonate reacts with sodium chloride to form a molecule of ammonium chloride and sodium bicarbonate precipitation, sodium carbonate is precipitated because it is less soluble.

Q: What are the important physiological functions of inorganic salts in cells: As a result of metabolism, every day a certain amount of inorganic salts from a variety of ways out of the body, which will be added through the diet. The metabolism of inorganic salts can be judged by analyzing the concentration of blood, hair, urine or tissue. The role of inorganic salts in the human body is interrelated. In the appropriate concentration range beneficial to the health of people and animals and plants, lack or too much can cause disease, and disease and affect its metabolism, often increase its consumption. In China, the lack of calcium, iron and iodine is more common. Selenium, fluoride and other geochemical environment with the different, both the lack of disease such as Keshan disease and Kashin-Beck disease, teeth, etc., there are too many diseases such as fluorosis and selenium poisoning.

Q: Why does inorganic salts affect chemical degradation of organic wastewater: Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.

Q: what is the function of salts in DNA extraction?: The role of the salt is to neutralize the charge of the DNA's sugar phosphate backbone. This makes the DNA less hydrophilic (less soluble in water). Ethanol has a lower dielectric constant than water so it's used to promote ionic bonds between the Na+ (from the salt) and the PO3- (from the DNA backbone) causing the DNA to precipitate, to extract DNA finally..
