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:Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
Speaking of calcium, many people will think of white calcium or calcium carbonate powder, and even rich in calcium food, often people mention nothing more than white milk and tofu. In fact, in the high calcium content of food, in addition to shrimp, most of the other looks very black. Every 100 grams of food in the calcium content of more than 300 milligrams of food with kelp, seaweed, Nostoc, black fungus, black sesame and other black food, and some calcium content even up to thousands of milligrams, and milk calcium content is only in the middle level , About 100 grams per 100 grams of calcium. People's Liberation Army 305 Hospital Digestive Medicine chief physician Wang Zhijin said that these black food calcium content is indeed high, but the taste, taste less than some milk, some people, especially young people do not love to eat. And calcium can not just look at the content of calcium, the most important thing is the absorption of the human body, at this point, the advantages of milk is very obvious. The nutritional content of each food is not a single, milk in the same calcium supplement, but also provide a lot of protein, amino acids, fat and vitamins, and kelp is rich in iodine, black fungus has now become an effective prevention of heart Cerebrovascular disease one of the foods.
Q:Can you die breathing in salt?
The boiling point of salt is incredibly high. Like thousands of degrees Celsius high. If you can actually manage to boil salt I would not recommend inhaling it.
Q:Several kinds of inorganic salt food sources?
Pepper, bamboo, bamboo, seaweed, lily, nuts, bread, dairy, beans, seaweed, kelp, kelp, Olives, cauliflower, amaranth, shepherd's purse, salted egg, noodles, fermented bean curd, tempeh, spinach, amaranth, spinach, coriander, fruit
Q:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological function of fat: 1. The supply of human heat. (Per gram of fat oxidation can produce 9 kcal of calories, protein and carbohydrates produce more than 2 times.) 2. constitute the body's adipose tissue, adjustable body temperature, To prevent the body outside the scattered, to protect the internal organs, moisturizing the skin. 3. Dissolve nutrients. (Some do not dissolve in water and only soluble in lipids, only in the presence of fat can be absorbed by the body.
Q:What foods contain zinc-containing inorganic salts
No. 4: Chibi (11.58 / 34g / 100g)
Q:Is the conduction of excitement on neurons related to inorganic salts?
Neurons, also known as nerve cells, constitute the basic unit of the nervous system structure and function.
Q:does the water solubility of an inorganic salt increase or decrease as the temp of the water is increased. Exp?
Usually solubility will increase with increasing temperature but there are a significant number of exceptions which show the opposite.
Q:What is the difference between organic salt and inorganic salt?
An organic salt contains a cation or anion that is derived from an organic compound (compounds that contain carbon), e.g. acetate (anion) from acetic acid, or triethyl ammonium (cation), from triethylamine. An inorganic salt is one that doesn't contain an organic cation or anion. Carbonates are not considered organic compounds, even though they contain carbon.
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.
