Q: How does inorganic salts maintain osmotic pressure and pH: PH ~ inorganic salts of carbonates bicarbonate, hydrogen phosphate / dihydrogen phosphate, can help regulate the pH value of the internal environment, even if the external environment Zoumu changes, the environment will not change too fast, there will be a Buffer room

Q: Are fruits and vegetables inactive?: Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, including constant elements of iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8. Apple, pipa, durian, citrus, Watermelon, kumquat, peanuts, I know so much. Oh, there are: lotus lotus which contain inorganic salts

Q: What fruit contains more minerals?: Kiwi fruit, tender and juicy fruit, sweet and delicious, sweet and sour and very nutritious, and its vitamin C content of up to 100-420g / 100mg, citrus, apple and other fruits several times or even several times, but also contains a large number of Sugar, protein, amino acids and other organic matter and the human body needs a variety of minerals.According to the United States Rutgers University Food Research Center test, kiwi fruit is the most nutritious nutrient content of the most comprehensive fruit.

Q: Organic chemistry extraction lab. If the KBr wasn&#39;t there I would just add HCl to protonate the NH2, but I&#39;m not sure if that will affect the KBr or the carbon chain. Both of these are in an aqueous phase.: The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.

Q: How to add inorganic salts: Helicobacter pylori can cause a variety of stomach problems, including gastritis, gastric ulcer, duodenal ulcer, non-ulcerative indigestion, gastric cancer. Therefore, the eradication of Helicobacter pylori has become an important measure for the treatment of modern gastrointestinal diseases. To identify patients with Helicobacter pylori infection, the clinical need for a high sensitivity, specificity, fast, simple, safe, inexpensive Hp diagnostic method, that is, carbon 14 breath test. The examination and painless, noninvasive, fast and simple, no cross the advantages of infection, experts at home and abroad have been recommended for the diagnosis of Hp gold standard, has been widely used in clinical practice.

Q: The lack of symptoms and food sources of several inorganic salts: Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.

Q: What is the disease of inorganic salt crystals?: It is recommended to drink boiled water.No need to take medication.

Q: The addition of inorganic salt viscosity of micelles increased first and then increased again and then reduced, there is no possibility ah? Yes, then what is the reason for the increase ah?: possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...

Q: What is the use of inorganic salts in plants? How is it discharged: Nitrogen is the constituent of chlorophyll, chlorophyll a and chlorophyll are all nitrogen compounds. Green plants for photosynthesis, so that light energy into chemical energy, the inorganic (carbon dioxide and water) into organic matter (glucose) is the role of chlorophyll. Glucose is the raw material for the synthesis of various organic substances in plants, and chlorophyll is the factory for the manufacture of "grain" for plant leaves. Nitrogen is also an integral part of vitamins and energy systems in plants. The transpiration of plants, taken away by water, is similar to human sweating
