Q:Inorganic salt is not salty: HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.

Q:I had asked a similar question on GC operation last week, but for different kinds of compounds.For my biochem research project at school, I&#39;m testing the ability of a species of bacteria to biodegrade alcohols found in gasoline (methanol, ethanol, isopropyl, tert-butyl and cyclohexanol). The bacteria is growing in a solution of minute amounts of alcohols and Mineral Medium, which is basically just water and dissolved inorganic salts (CaCl2, KH2PO4, NH4NO3 and MgSO4).I know GC&#39;s are primarily used to separate organic mixtures. Can a GC separate organic compounds dissolved in salt water? Is it safe to put salt water in a GC? Or would I have to do an extraction to separate the alcohols and run the organic extract through the GC?: Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.

Q:What are the physiological functions of inorganic salts: Maintain cell osmotic pressure and acid-base balance

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:After a lot of sweating, the amount of drink with inorganic salt drink right?: It is best to drink this kind of drink, which contains sodium and potassium, and when the body after a lot of exercise will consume a lot of potassium, leaving the body feel weak, this drink can quickly add the body Electrolyte, need to note that before the exercise 1-2 hours, during exercise and after exercise have to drink

Q:Why plasma osmotic pressure and protein, inorganic salt content: The crystal osmotic pressure is determined by the content of inorganic salts; colloid osmotic pressure is mainly determined by the protein content, especially albumin.

Q:Is urea an inorganic salt?: Is not organic matter ah inorganic salts are present in the body and food minerals in the mineral, composed of organic matter and inorganic synthesis of the human body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. More (> 5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven; daily dietary requirements are more than 100mg, known as constant elements. Other low content, with the modern analysis of technological progress Iron, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements were found by atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods. But also the human body is necessary, the daily dietary requirements for the amount of μg ~ mg called trace elements.

Q:Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference: GB / T5009.4-2003 "Determination of ash in food" (a) the principle of a certain amount of samples after carbonization into the high temperature furnace burning, the organic matter is oxidized decomposition to carbon dioxide, nitrogen oxides and Water and other forms of escape, and inorganic substances to sulfate, phosphate, carbonate, chloride and other inorganic salts and metal oxide in the form of residual

Q:Definition of inorganic salts: There are about 21 kinds of elements which have important physiological functions in the body. Among them, calcium, magnesium, potassium, sodium, phosphorus, sulfur and chlorine are more and more, and the amount of inorganic compounds is more Iron, copper, iodine, zinc, manganese, selenium, fluorine, chromium, nickel, molybdenum, silicon, tin, vanadium and cobalt content is extremely small, called trace elements .2, inorganic compounds in the general name of the salt. Formerly known as "minerals." Some elements of inorganic salts for the human essential nutrients, including potassium, sodium, calcium, phosphorus, iron, iodine and other 20 kinds of elements. With the maintenance of cells and liquid normal osmotic pressure, maintenance of neuromuscular excitement As a variety of acid system activator; constitute the ester of the base; hormones, vitamins, nucleic acid composition and regulate the body's acid and alkali balance and other important physiological functions. Increased or lack of disease, such as hyperkalemia, The explanation of the "inorganic salts" in the academic literature

Q:What is the time when the maximum number of inorganic salts is needed: Nitrogen is the basis of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll, enzymes, vitamins, alkaloids and some hormones, etc. Nitrogen is also the basis of genetic material. In all organisms, the protein is most important, it is Often at the center of metabolic activity, which is the primary factor limiting plant growth and yield, and has a significant effect on improving product quality.
