- Q: What are the disadvantages of inorganic salt deficiency and too much
- high calcium, hypercalcemia can make nerve, muscle excitability to reduce the performance of fatigue, expression indifferent, tendon reflexes, severe patients may be mental disorders, stupor and coma; damage renal tubules, manifested as kidney Tubule edema, necrosis, basement membrane calcification, can cause kidney stones;
- Q: What are the important physiological effects of inorganic salts in cells
- Composition of cells in some important compounds,
- Q: General identification method of inorganic salts
- Take the test solution, add thiocyanate solution solution, that is blood red. Fe3 + + NH4SCN → Fe (SCN) 2 + (blood red) Take the test solution, plus potassium ferrocyanide test solution, that is, white precipitate, separation, precipitation in dilute hydrochloric acid insoluble. 3Zn2 ++ 2K4 [Fe (CN) 6] → K2Zn [Fe (CN) 6] 2 ↓ (white) + 6K +
- 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: The inorganic salt is composed of?
- Inorganic salts are the general term for various inorganic salts. They are composed of inorganic acid radicals and metal cations or ammonium salts, mainly salts of organic acid salts, such as sodium chloride, potassium chloride and so on.
- Q: Is all the inorganic salts in the body related to life activities?
- Sugar is the most important material for the human body, all the activities of the human body, including learning, walking, digestion and breathing, etc., which are the most important substances in the human body. Consumption of energy (about 70%) mainly from the carbohydrates, fat is the body of the energy material, the protein is the basic material of human cells, but also to provide energy, vitamins are neither the main raw material of the organization, nor the supply of energy Material, but it has an important role in the life activities of the human body; inorganic salts constitute an important raw material of human tissue, water is the main component of cells. Which protein, sugar, fat, vitamins can burn for organic matter, and water, inorganic salts can not burn as inorganic.
- Q: I am a candidate for this year's Harbin City, Jiqiu the standard answer, tomorrow I will test !!!
- The distribution of inorganic salts in the human body is extremely uneven. For example, calcium and phosphorus are mostly in hard tissue such as bone and teeth, iron is concentrated in red blood cells, iodine is concentrated in the thyroid, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue.
- Q: Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
- Soy products containing more calcium. Animal liver, spinach iron, zinc and so on.
- Q: I am 18 years old, test the body of inorganic salt content of 3KG, people say that low. What is the value of this use? How can improve it?
- The percentage of inorganic salts in human mass is 4 to 5%
- Q: The difference between the ignition of inorganic salts and organic matter
- Will the ignition of inorganic matter and the ignition of organic matter, thank you
