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:The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is
Due to dry conditions are not complete, the lack of text, can not be a normal answer.

Q:Definition of inorganic salts
In addition to hydrogen, oxygen, nitrogen, carbon, sulfur, organic compounds other than organic compounds are collectively referred to as inorganic salts. The inorganic salts required by the human body, according to the content in the body, divided into essential elements (hydrogen, oxygen, nitrogen, , Magnesium, phosphorus, chlorine, potassium, sodium 11) in the human body content, the need for larger also known as macro elements of the source 2, the rest of the various elements, regardless of content, can be collectively referred to as inorganic salts. More elements such as iron, magnesium, potassium, sodium, phosphorus, sulfur, chlorine and other elements, other elements such as iron, copper, iodine, zinc, manganese, drilling, etc., due to the existence of a small number, and some even trace Known as trace elements, 3, what is the "inorganic salt", the body contains elements in addition to carbon, hydrogen, oxygen three elements mainly in the form of organic matter, the rest of the various elements are in the form of inorganic matter, collectively referred to as inorganic Salts such as calcium, magnesium, potassium, sodium, phosphorus, scratch, sulfur and the like
Q:How to isolate the effects of inorganic salts on enzyme solubility
The effect of inorganic salts on the solubility of the enzyme was studied. The inorganic raw materials were pretreated with inorganic salts to separate the solid-liquid phase, and some of the lignin and hemicellulose were dissolved, and the sulfuric acid and the inorganic salt were added to the cotton Treatment, thereby improving the enzymatic hydrolysis efficiency. Using different amounts of sulfuric acid
Q:Inorganic salt is not salty
HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.
Q:Does the inorganic salt affect the gpc molecular weight results?
GPC determination of molecular weight through the column when the molecular size of the molecular peak, the molecular weight of the early comparison of the peak, that is relatively large molecules in the GPC pillars can not pass, pass the molecules were detected out of the peak, This molecular weight is not absolute, since the GPC determination is actually the size of the molecule rather than the size of the molecule, and of course it is also possible to approximate the molecular weight of the molecular weight of the molecule. Large; exactly how their relationship, with GPC can not be determined, only through the standard liquid molecular weight to compare, this result is relative, not absolute.
Q:Does the urine and urine contain inorganic salts? Anxious
Analysis: This question can be solved from the formation of urine. Kidney is the formation of urine organs, nephrons are the basic unit of renal structure and function, nephrons include glomerular, renal sac and renal tubules; urine formation process, including filtration, reabsorption and secretion of three processes.
Q:The application of various inorganic salts in the human body?
All tissues of the human body contain strontium, is also the main component of bone and teeth, mainly gathered in the ossification of the place, can be strong bones.
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 sugar and salt organic or inorganic?
Depends upon the source. Sometimes salt and sugar have added things. Look for the words certified organic to make certain.
