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: For example, sulfates can emit SO2 or SO3 gas. If this were to occur in this experiment, would the % H2O calculated from the data be too high or too low? Explain.
You would measure the mass lost, and you would assume that this is equal to the amount of water that was in the sample. So decomposition would add to the mass lost during heating and this would lead you to overestimate the amount of water that was in the sample, and overestimate the %h20.
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: Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
Three by: the beaker close to the glass rod;
Q: what is the function of salts in DNA extraction?
DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.
Q: ATP components are not inorganic salts
ATP components are not inorganic salts
Q: What are the main physiological functions of inorganic salts?
to maintain the organization's normal excitability
Q: is sugar and salt organic or inorganic?
sugar is organic salt is not. Sugar is made from carbon that's why it's organic in compound
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.
Q: as a example potesium,sodium,magnees,calcium
The sodium-potassium pump is most important in controlling the working of neurotransmitters. Calcium ion is also generated in voltage gated Ca++ channel, and Magnesium is necessary for metabolic functions. But Sodium is one of the most important inorganic component in our body. Of course Potassium is also as important. But, if you have ever seen the back of all food products there is a special part showing amount of Sodium in it...even Snacks.. :)
Q: Does the apple contain inorganic salts and vitamins?
Yes, the fruit is rich in these two nutrients, especially apples
