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 effect of inorganic salt medium and the difference with enrichment medium
The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.
Q:What is the difference between inorganic and inorganic salts?
Organic matter is defined as: all substances that are carbon-containing substances, organic substances other than carbon dioxide, carbonates, carbon monoxide, cyano substances, elemental carbon itself, etc. are generally used in the field of organic chemistry, including natural generation Of organic matter and synthetic organic matter (especially polymer-based organic matter)
Q:I measured in the gym today in the inorganic salt protein moisture is lower than the normal value of what is the reason
The gym can also be measured
Q:what percent of dissolved salts found in seawater are minor inorganic salts, or trace?
Seawater varies in composition a little but generally is about 3.5% salts. Of this about 3.1% is sodium chloride. So the remaining 0.4% is the other salts (Magnesium, Calcium and Potassium mostly, followed by just about every natural element in the periodic table in trace amounts)
Q:Does the milk contain inorganic salts?
Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element
Q:What foods contain inorganic salts?
Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice and so on.
Q:What is the disease of inorganic salt crystals?
But if the urine turbidity, but also accompanied by fever, low back pain, increased frequency of urination and other phenomena, there may be inflammation of the urinary system, should go to the hospital for timely diagnosis and treatment of doctors.
Q:What to eat can promote the absorption of inorganic salts
Transpiration on the absorption of inorganic salts has little effect, the book or which exercises on the image shows the problem
Q:Do inorganic mercury salts bioaccumulate?
Yes they do bioaccumulate. Mercury builds up for years and years, and eventually sits in a residue of pure mercury. - JJ
Q:Is bromine an inorganic salt?
Bromine is an inorganic element & forms salts for e.g.with Sodium to form Sodium bromide. It's a highly corrosive liquid & dangerous to handle. It's made from mother liquor - liquid got after extraction of solar salt from highly cocentrated brine.
