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: and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^)
- I think organic compunds are anything with Carbon(C), although I really don't know.
- Q: Why plasma osmotic pressure and protein, inorganic salt content
- The crystal osmotic pressure is determined by the content of inorganic salts; colloid osmotic pressure is mainly determined by the protein content, especially albumin.
- 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: What is the time when the maximum number of inorganic salts is needed
- The content of phosphorus in plants is lower than that of nitrogen and potassium, and is generally higher in seeds. Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis in plants , Respiration, energy storage and delivery, cell division, cell enlargement and other processes.
- 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: Advertisements related to inorganic salts -.-,
- Calcium must be inorganic salt
- Q: I had asked a similar question on GC operation last week, but for different kinds of compounds.For my biochem research project at school, I'm testing the ability of a species of bacteria to biodegrade alcohols found in gasoline (methanol, ethanol, isopropyl, tert-butyl and cyclohexanol). The bacteria is growing in a solution of minute amounts of alcohols and Mineral Medium, which is basically just water and dissolved inorganic salts (CaCl2, KH2PO4, NH4NO3 and MgSO4).I know GC's are primarily used to separate organic mixtures. Can a GC separate organic compounds dissolved in salt water? Is it safe to put salt water in a GC? Or would I have to do an extraction to separate the alcohols and run the organic extract through the GC?
- Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.
- Q: is sugar and salt organic or inorganic?
- sugar is organic salt is not. Sugar is made from carbon that's why it's organic in compound
- Q: Is iodized salt inorganic or organic?
- "Iodized salt" is sodium chloride which contains minute amounts of iodine-containing salts. The most commonly added iodine salts are: potassium iodate, potassium iodide, sodium iodate, and sodium iodide. All of these compounds are inorganic. By the way, while methyl iodide is organic, it is not a salt.
