2.Main Features of Sodium Hydrosulfite：
It is a versatile chemical that's used in the manufacture of a variety of products we all use every day,
from photographic film to wine; from fine writing papers to leather goods; from colored fabrics to metal recovery.
While the applications for this chemical workhorse are as vast and as varied as the industries that use it,
in most cases, sodium hydrosulfite performs one of the following three roles:
1) As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons
2) As sulfonating agent, hydrosulfite adds sulfur to another chemical compound
3) As cation source, hydrosulfite adds a cation, or sodium, to a product system

- Q: How does inorganic salts maintain osmotic pressure and pH
- Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
- Q: For patients with ulcerative colitis, which inorganic salt foods can eat?
- Human nutrient needs a variety of inorganic salts (also known as minerals), part of the food from the moving, plant tissue, part of the water and salt. The chemical nature of inorganic salts in food is very stable, not like vitamins as heat, light, oxygen and decomposition of the role of oxidation, but if the processing method is not appropriate, will cause many losses.
- Q: I will eat a boiled egg every morning, drink a box of milk before going to bed at night, to stop these things, eat only vegetables?
- This is not accurate, the reference, I measured is 12.3, the normal range is 9.8 to 11.8kg it! You see your normal range, estimated machine different
- Q: What inorganic salts and trace elements are there in rice?
- Sodium (2.40 mg) of copper (2.30 micrograms) of copper (2.10 mg) of copper (1.10 mg) of zinc (1.45 mg) of copper (2.40 micrograms)
- Q: What fruit contains more minerals?
- Watermelon fruit contains 90% or so, so there are "watermelon," said watermelon contains a variety of nutrients and chemical substances. Watermelon pulp contains protein, sugar, crude fiber, potassium, phosphorus, calcium, iron, sodium, magnesium Chlorine, niacin, vitamin A, vitamin B1 and vitamin B2 in the watermelon juice also contains citrulline, alanine and glutamic acid and other amino acids, malic acid and other organic acids, pectin and a small amount of glycosides, and Medlar, cinnamon and other alkaloids and so on.
- Q: The lack of symptoms and food sources of several inorganic salts
- Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.
- Q: how come a penny can hold more drops of the salt water solution than just plain tap water from your faucet?
- Put in in a narrow tube. The narrower it is, the more surface tension it has at the meniscus.
- Q: Why does inorganic salts affect chemical degradation of organic wastewater
- Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.
- Q: would heterotrophic organism grow well in inorganic salt media? why or why not?
- No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
- Q: The power of the water and inorganic salts in the plant is derived from the action of the plant
- The main process is: soil moisture → root hair → root catheter → stem catheter → leaf catheter → stomata → atmosphere.
