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: Urine in the inorganic salt content is higher than the original urine
- A large amount of water and inorganic salts are recovered
- Q: The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is
- wrong. Can only promote the transport up! Can not promote absorption.
- Q: What fruit contains more minerals?
- Kiwi fruit, tender and juicy fruit, sweet and delicious, sweet and sour and very nutritious, and its vitamin C content of up to 100-420g / 100mg, citrus, apple and other fruits several times or even several times, but also contains a large number of Sugar, protein, amino acids and other organic matter and the human body needs a variety of minerals.According to the United States Rutgers University Food Research Center test, kiwi fruit is the most nutritious nutrient content of the most comprehensive fruit.
- Q: What are the effects of inorganic salts on plant growth?
- P: to promote the development of seedlings and flowers open, so that the fruit, the seeds mature early. Lack of performance: the plant is particularly short, leaves were green, and purple.
- Q: How can experiments prove that there are inorganic salts in the leaves of plants
- The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.
- Q: Is bromine an inorganic salt?
- Bromine is analogous to table salt.
- Q: The inorganic portion of bone tissue is made of what complex mineral salt ?
- hydroxyapatite - Ca10(PO4)6.(OH)2 - which covers the calcium and phosphorous that are needed for bone development And just so you know, plants don't have "bones" - your question was posted in Botany.
- 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
- Absorbed in an ionic state.
- Q: What is the disease of inorganic salt crystals?
- But if the urine turbidity, but also accompanied by fever, low back pain, increased frequency of urination and other phenomena, there may be inflammation of the urinary system, should go to the hospital for timely diagnosis and treatment of doctors.
- Q: I am told to find which bottled mineral water brands contain the most mineral salts.But im not sure if the mineral salt here is talking about the common table salt (Sodium Chloride) or the chemical salt (ionic compounds such as sulfate and chloride) or the whole list of dietary minerals (potassium, chlorine, calcium, magnesium, ect.) I normally think it is just the table salt but im afraid I might get wrong. So what is the exact definition?
