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:

1As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons

2As sulfonating agent, hydrosulfite adds sulfur to another chemical compound

3As cation source, hydrosulfite adds a cation, or sodium, to a product system

Q:Each of the fallowing is an example of an inorganic compound except one? A)water. B) bases). E)enzymes. D)salt?
anything which contain carbon is organic. so enzyme is the odd one out.
Q:A colorless solution contains which inorganic salt?
Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.
Q:What is the composition of inorganic salts?
Inorganic salts are inorganic compounds in the salt, formerly known as minerals
Q:Does the plant roots absorb inorganic salt ions must be active
Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. 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 are the disadvantages of inorganic salt deficiency and too much
high blood magnesium, muscle weakness, limb muscle soft paralysis, affect the respiratory muscle, respiratory failure can occur, respiratory arrest; severe central inhibition, such as lethargy, stupor, coma, etc .; can lead to various arrhythmias ; May produce bloating, constipation, nausea, vomiting, etc .;
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:Is the conduction of excitement on neurons related to inorganic salts?
Neurons are cells with long synapses (axons) that consist of cell bodies and cell processes. In the long axon with a layer of sheath, composed of nerve fibers, it is a small branch of the end called nerve endings. Cell bodies are located in the brain, spinal cord and ganglion, the cell processes can be extended to the body organs and tissues. The cell body is a nuclear part of the cell, its size is very different, about 4 to 120 microns in diameter. Nuclear large and round, located in the central cell, less chromatin, nucleolus obvious. There are plaque outside the cytoplasmic chromatin (formerly known as Neil body), there are many neuronal fibers.
Q:Which crop feet can provide C N inorganic salts for fungal growth
Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
Q:What does salt form when it dissolves?
Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.
Q:ATP components are not inorganic salts
ATP is composed of adenosine and three phosphate groups, chemical formula C10H16N5O13P3, structural formula C10H8N4O2NH2 (OH) 2 (PO3H) 3H, molecular weight 507.184. Three phosphoryl groups are prepared from adenosine as alpha, beta and gamma phosphates. ATP is chemically named 5'-triphosphate-9-β-D-ribofuranosyladenine, or 5'-triphosphate-9-β-D-ribofuranosyl-6-aminopurine.
