Appearance: white powder, 325-3000 mesh
Application: It can be used as the raw materials or fillers in oil paint,ink,plastic,rubber and battery ,the Surface smear medicament of the Printing paper and copper board , and sizing agent for textile industry. As clarifying agent,it can play a role of anti-foaming and increase the glossy of glass products. It also can be used as an anti-radiation protective wall materials. In addition,it’s widely used in pottery , enamel, spices and paints, etc. What’s more, it can be used as the raw materials to produce other barium salts.

- Q: Urine in the inorganic salt content is higher than the original urine
- The amount of urine is much less than that of plasma, and the total urea content is not higher than that of plasma, and it is difficult for renal tubules to be reabsorbed
- Q: I'm said that with the increase of temperature the inorganic salts will decrease. Will that be correct?
- IIRC, it depends on the salt.
- Q: bonded to an acid molecule called- such as potassium citrate?Thanks
- all metals like potassium,sodium,iron,magnecium etc are minerals
- 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: Advertisements related to inorganic salts -.-,
- Three crystal good mother know every night to give her blue bottle, and help absorb the blue screen of the drink, Harbin Pharmaceutical six factory production.
- Q: Consult the science and engineering, chemical and biological experts, plants absorb inorganic salts and water, then the absorption of inorganic salts in what form is absorbed into the way, is absorbed in the way of ions or in the way of the compound, And then only in the body only ionized into the ion state exists in the body. Grateful
- Root cell cell concentration is high, with the external soil moisture to form osmotic pressure, resulting in water and dissolved in water in the inorganic salt flow to the root cells, the absorption method is in the form of dissolved, so it is in the form of ions. If the salt can not be dissolved can not be absorbed, as for the specific water and inorganic salt transport can refer to 2017.7.25 know the daily newspaper.
- Q: Is the inorganic salt related to the excitement
- Human or animal body nerve cells are stimulated, excited in the form of electrical signals in the nerve fiber conduction process.
- Q: Think about the physical and chemical properties of salt and sugar. What properties do these substances have in common? Describe which properties you could use to distinguish between them. What properties and units would you use to describe their physical and chemical characteristics? List as many as you can.
- I believe it's Physical, most of the times such changes are physical, melting point, sublimation, evaporation, etc.
- Q: what is the function of salts in DNA extraction?
- DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.
- Q: Which minerals is richest source of Inorganic Salts ?
- Minerals are inorganic salts - eg.potassium nitrate - absorbed by plants from soil - a good source of inorganic nitrogen and potassium.
