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 to get an inorganic salt
- Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
- Q: Like the role of B, Fe, Mg, Ca, Mn, Cu, Cl, P, S, N ...., the more specific the better (college entrance examination range)
- Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable.
- 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 is the most important inorganic salt in plant growth?
- The inorganic salts required by plants are nitrogen, phosphorus and potassium containing inorganic salts, and if any lack of plants will affect the normal growth of plants, nitrogen is a component of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll , Enzymes, vitamins, alkaloids and some hormones contain nitrogen. Nitrogen is also the basis of genetic material in all organisms, the most important protein, it is often in the center of metabolic activity.Now is to limit the growth of plants and the formation of the primary Factor. It also has a significant effect on improving the quality of the product.K2 is dissolved in the plant juice, and its main function is related to the metabolism of the plant.The content of phosphorus in the plant is second only to nitrogen and potassium, Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis, respiration, energy storage and delivery, cell division, cell enlargement and other processes in plants.
- Q: I am an AP biology student testing how magnesium effects the rate of photosynthesis in a plant. However since my class period is only one hour long I highly doubt if i add epsom salt to the soil ( after mixing it with water) i will see an immediate increase in the rate of photosynthesis. So i need to know how long should i wait to test photosynthesis rates after adding an epsom salt solution to the soil of a plant. Or how long does it take for magnesium to be incorporated into a plants rate of photosynthesis. Thanks in Advance!
- Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth. Rate of photosynthesis does not depend upon any single factor . so it is futile to expect it should increase after addition of epsom salt to soil in solution form . Because first it should be incorporated in chlorophyll molecule . That depends upon formation of new leaves . Old leaves already have it ( formula of chlrophyll a = C55 H72 O5 N4 mg ) That is the requirement is just one atom per molecule . what to do with excess ? Unless the soil is deficient in Mg . It it useless to add it . soil pH is another factor to be considered = Soil pH (a measure of the acidity or alkalinity of the soil) Soil pH is one of the most important soil properties that affects the availability of nutrients. Macronutrients tend to be less available in soils with low pH. Micronutrients tend to be less available in soils with high pH. www.ncagr /cyber/kidswrld/plan...
- Q: Does the plant absorb some of the inorganic salt?
- Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
- Q: what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
- For the best answers, search on this site www.okorder You're a riot, I swear. It amazes me how many people completely miss your plays on words. I'd stick with the "in" organic food. You know, the really trendy stuff like chai tea. Stay away from old, tired standbys like pizza and hamburgers. Macaroni and cheese, though, is like the tuxedo or the little black dress. It never goes out of style.
- Q: List the major electrolytes released by inorganic salts when placed in water and explain how these electrolytes are needed for metabolic reactions.
- Which "inorganic salts" are you talking about? There are hundreds!
- Q: in the ocean
- Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.
- Q: Is iodized salt inorganic or organic?
- yes it is organic.
