Q:What is the use of inorganic salts and organic salts?
The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.
Q:What is the physiological function of inorganic calcium
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:are acids, bases, salts and oxides belong to inorganic compound?
Any carbon-containing compound is considered organic with the exception of carbonates, bicarbonates, carbon dioxide and carbon monoxide.
Q:During the different periods of plant growth, the amount of water and inorganic salt required is different.
Plant life, although the need for a variety of inorganic salts, but different plants on the various types of inorganic salt requirements are different, such as cabbage, spinach and other human needs leaves of vegetables need nitrogen containing inorganic salts, tomato, peanuts need phosphorus Of the inorganic salt and more, sweet potatoes, potatoes need potassium-containing inorganic salts; the same plant with the growth period of the different requirements of inorganic salts are not the same, for example, plants in the seedling period requires nitrogenous inorganic salts , In the flowering, the results of the period of time need more phosphorus-containing inorganic salts. Therefore, different plants and the same plant growth period, the need for inorganic salts are different. So the answer is: different; different
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:What are the nutritional requirements for bacterial growth?
For inorganic salts: bacteria need a variety of inorganic salts to provide a variety of elements of bacterial growth, which requires the concentration of 10.3 ~ 10.4mol / L elements for the common elements, the need for concentration in the
Q:Can inorganic salts act as stabilizers for emulsified asphalt?
Heze Tongren Road Machinery Co., Ltd. is a asphalt heating and storage equipment as the main body, set road maintenance equipment production, asphalt library design and transformation of technical services, to undertake asphalt library / depot and other construction and installation, industrial pipelines and chemical equipment The installation of the installation of the boiler, the installation of steel structures and accessories sales, such as integrated services in one company.
Q:Indicating the organic compounds and inorganic salts in the boiling point, melting point and solubility of what is the difference
Organic compounds are mainly covalently bonded, the mutual attraction between molecules is very weak, so its melting point, low boiling point, generally insoluble in water and soluble in organic solvents. Inorganic salts with ionic bonding, positive and negative ions electrostatic attraction is very strong, so the melting point, boiling point is very high, usually insoluble in organic solvents and soluble in water.
Q:Why is sodium chloride(salt) an inorganic compound?
This is because NaCl does not contain Carbon. It is usually compounds that contain Carbon which can be considered ORGANIC compounds. :)
