- Q:The effect of inorganic salt medium and the difference with enrichment medium
- The enrichment of nutrients is based on the basis of nutrition based on some kind of nutrient-rich substances for the target cells, the purpose is to increase the number of target cells, so that the formation of growth advantages, so as to achieve the purpose of separation, such as we have to be separated Pseudomonas aeruginosa, this bacteria particularly like blood, so you can add blood in the medium, so that the formation of growth advantages of this bacteria.
- Q:What is the difference between "organic salt" and "inorganic salt"?
- Inorganic salts that inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, of which constant elements are iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8 species. If you pay attention to diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, the body can make the inorganic salt to maintain the normal level. Organic salts Organic salts are organic groups plus metal cations or non-metallic cations, such as sodium acetate, sodium ethoxide, ammonium acetate, and inorganic salts are formed by simple inorganic anions plus cations such as sodium chloride Wait.
- Q:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolyte?
- Which "inorganic salts" are you talking about? There are hundreds!
- Q:Why is the inorganic salt left after the burning of the food
- Food contains protein, fat, inorganic salts and water and other substances in the process of combustion in addition to inorganic salts and the rest of the water are burned, and water in the combustion process evaporates. So take the only inorganic salt.
- Q:Why can quaternary ammonium salts catalyze the heterogeneous reaction between water-soluble inorganic salts and organic compounds
- Quaternary ammonium salts have the characteristics of surfactants, with the water phase of the nucleophile in the composition of the ion pair, into the organic phase, thereby promoting the heterogeneous reaction faster 6224
- Q:give me examples of organic, inorganic, acid, base, salt.?
- Organic acids: acetic acid(vinegar), oxalic acid. citric acid(lemon), butaric acid, propionic acid. Inorganic Acids: Hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, hydrobromic acid. Bases: sodium hydroxide, potassium hydroxide, calcium hydroxide, ammonia, magnesium hydroxide. salts: table salt (sodium chloride), potassium fluoride, barium sulfate, magnesium bromide
- Q:The application of various inorganic salts in the human body?
- Iron is an essential trace element in the animal body and plays an extremely important role in the metabolism of animals.It is not only a component of a variety of compounds but also a variety of metabolic-related enzyme activities, and to a certain extent The immune function of the body.
- Q:What are organic and inorganic salts?
- Salt is a mineral from the Earth. Salts similar to iodized are extra munufactured and aren't fully typical. However salts like sea salt have the leat amount of processing. Some say that sea salt is healthier since it's he most traditional state of salt that you could get in mass production. I wolud must agree with them.
- Q:The presence of inorganic salts
- The presence of inorganic salts is mostly present in the ionic state in a small number of compounds
- Q:What are these salts used for please?
- HI I'M PNT. LITHIUM SULFATE is a white inorganic salt with the formula Li2SO4. It is used to treat bipolar disorder. It is soluble in water, though it does not follow the usual trend of solubility versus temperature — its solubility in water decreases with increasing temperature . This property is shared with few inorganic compounds, such as the lanthanoid sulfates. Lithium sulfate crystals, being piezoelectric, are also used in ultrasound-type non-destructive testing because they are very efficient sound generators. However they do suffer in this application because of their water solubility. ZINC NITRATE: Zinc nitrate (Zn(NO3)2) is a chemical compound used as a mordant in dyeing. It is also a source of zinc ions for chemistry. An example reaction gives a precipitate of zinc carbonate:Zn(NO3)2 + Na2CO3 → ZnCO3 + 2 NaNO3. Conditions/substances to avoid are: reducing agents, organic materials, metal powders, heat and flame, cyanides, sodium hypophosphite, tin(IV) chloride, phosphorus, thiocyanates, carbon, and sulfur. Its Relative Molecular Mass is 189. SODIUM PHOSPHATE: Sodium phosphate are forms of phosphorus, which is a naturally occurring substance that is important in every cell in the body. Sodium phosphate is used to treat constipation and to clean the bowel before surgery, x-rays, endoscopy, or other intestinal procedures. Sodium phosphate enemas are also used for general care after surgery and to help relieve impacted bowels. Sodium phosphate may also be used for other purposes not listed in this medication guide REGARDS, PNT.
