- Q: After running the training is best to drink what drinks add inorganic salt
- You say drink, personally feel good luck!
- Q: Seaweed, kelp, shrimp and other seafood, the content is more of the kind of inorganic salts
- Inorganic salts in the human body is very small, but the role is very large, if the lack of suffering from the corresponding diseases, such as iodine deficiency susceptible to big neck disease, kelp, seaweed and shrimp and other seafood iodine is rich; More calcium; spinach rich in iron; nuts, liver and other zinc more.
- Q: Is calcium carbide inactive?
- Calcium carbide, the chemical formula for the CaC2, not inorganic salts. Salt refers to the metal ions and acid ions of the compound, calcium carbide does not have the corresponding acid.
- Q: A bit tall please help me one!
- China Battery Industry Association executive vice president and secretary general Wang Jingzhong pointed out: "green alkaline alkaline manganese battery products," the introduction of China's alkaline manganese batteries marked the main environmental indicators have reached the world advanced level. This time the introduction of alkaline manganese battery brand, the battery mercury content of 0.0001% below, and not contaminated soil mercury content close. Waste batteries have little impact on the environment. According to the State Environmental Protection Administration on October 9, 2003 announced the "waste battery pollution control technology policy" provides that the waste mercury-free alkaline manganese batteries can be mixed with domestic waste collection and landfill.
- 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: Recently, when I breathe feeling a bit of acid teeth, this feeling particularly uncomfortable, ask you what is the reason ah? What should I do? Thank you
- You use the mouth, breathing ah ???????? dentin allergy, enamel damage `` `` desensitized toothpaste try `` `` `not go to the oral hospital to fill up` ``
- Q: Why vegetables and fruits contain rich inorganic salts
- Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier
- Q: The addition of inorganic salt viscosity of micelles increased first and then increased again and then reduced, there is no possibility ah? Yes, then what is the reason for the increase ah?
- possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
- Q: What is alkali?
- What is the alkali is the ionic compound, the ionization of the anion is hydroxide (OH-), in fact, the oxygen ion acid root (which can compare sulfur and sulfur), and the anion contains only hydroxide. (Such as LiOH, NaOH, NH3 · H2O) soluble in water, alkaline earth metal ions formed in the periodic table from top to bottom gradually soluble [Be (OH) 2, the alkali metal ions or alkali ions, Mg (OH) 2 is insoluble, Ca (OH) 2, Sr (OH) 2 is slightly soluble, and Ba (OH) 2, Ra (OH) 2 is easily soluble, and other bases are in addition to TlOH and Tl (OH) Is difficult to dissolve alkali and acid metathesis reaction is also known as neutralization reaction, that is, H + + OH- == H2O
- Q: Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.
- The water and inorganic salts in the soil are absorbed through the root of the root of the root of the root of the root of the root, due to root pressure by the body of the fiber duct system to the plant roots, stems, branches, leaves, flowers, fruit parts Of the cells in the supply of nutrients.
