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: I'm said that with the increase of temperature the inorganic salts will decrease. Will that be correct?
- Usually solubility will increase with increasing temperature but there are a significant number of exceptions which show the opposite.
- Q: What is the inorganic salt in the egg
- Fat (g) .1 niacin (mg) .2 iron (mg 1.6
- Q: Does the inorganic salt fight the mass spectrum?
- Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
- Q: What fruit contains more minerals?
- Strawberry nutrient-rich, rich in a variety of active ingredients, per hundred grams of fresh fruit with vitamin C60 mg, than the apple, grape content is also high. Flesh contains a lot of sugar, protein, organic acids, pectin and other nutrients. , Strawberry is also rich in vitamins B1, B2, C, PP and calcium, phosphorus, iron, potassium, zinc, chromium and other essential minerals and some trace elements. Strawberry is the body of the necessary cellulose, iron, potassium, C and flavonoids and other important sources of ingredients.
- Q: What is the inorganic salt, is not the organic salt and is not the inorganic salt
- In fact, Na2CO3 is also inorganic salt ah! The Can not according to whether there is C to divide!
- 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: what is the function of salts in DNA extraction?
- The role of the salt is to neutralize the charge of the DNA's sugar phosphate backbone. This makes the DNA less hydrophilic (less soluble in water). Ethanol has a lower dielectric constant than water so it's used to promote ionic bonds between the Na+ (from the salt) and the PO3- (from the DNA backbone) causing the DNA to precipitate, to extract DNA finally..
- Q: How to extract inorganic salts in soil?
- Find a piece of mud, with water, filter out the permeate, filter with filter paper. The liquid was placed in a beaker and dried to obtain white crystals
- Q: What are the nutritional requirements for bacterial growth?
- For water: the nutrients required for bacteria must be dissolved in water, nutrient absorption and metabolism are required to carry out water.
- Q: My body fat rate 14.6 normal body fat percentage 31.2 is more than the normal value I do not know the difference between the two please God answer ah Thank you very grateful and then those elements of my lack of God is the situation ah I love meat is not a vegetarian! And I super love to eat eggs! And my super love to drink water!
- I am also a little lower inorganic salt so point, the coach said that usually drink some salt. Protein and water are low can only explain a problem, have a good fat under the conversion.
