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:Is the inorganic salt the same as the saline?
Saline is sodium chloride solution, most people use the point is 0.9%.
Q:Is it possible to adjust the internal temperature of the carbohydrate in the vacuole
the internal environment refers to the human cell life of the liquid environment, that is, extracellular fluid.
Q:What is the physiological function of inorganic calcium
Cells and organisms of the important components
Q:give me examples of organic, inorganic, acid, base, salt.?
Organic acids: acetic acid(vinegar), oxalic acid. citric acid(lemon), butaric acid, propionic acid. Inorganic Acids: Hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, hydrobromic acid. Bases: sodium hydroxide, potassium hydroxide, calcium hydroxide, ammonia, magnesium hydroxide. salts: table salt (sodium chloride), potassium fluoride, barium sulfate, magnesium bromide
Q:How long will it take for epsom salt to be incorporated into a plants rate of photosynthesis when addedto soil?
Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth. Rate of photosynthesis does not depend upon any single factor . so it is futile to expect it should increase after addition of epsom salt to soil in solution form . Because first it should be incorporated in chlorophyll molecule . That depends upon formation of new leaves . Old leaves already have it ( formula of chlrophyll a = C55 H72 O5 N4 mg ) That is the requirement is just one atom per molecule . what to do with excess ? Unless the soil is deficient in Mg . It it useless to add it . soil pH is another factor to be considered = Soil pH (a measure of the acidity or alkalinity of the soil) Soil pH is one of the most important soil properties that affects the availability of nutrients. Macronutrients tend to be less available in soils with low pH. Micronutrients tend to be less available in soils with high pH. www.ncagr.gov/cyber/kidswrld/plan...
Q:what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
The organic part is where blood cells are manufactured. The inorganic part is for structural strength
Q:Is the inorganic salt related to the excitement
Should be excited about conduction and inorganic salts. Membrane on both sides of the solution is conductive, in the excitement of the nerve segment and adjacent it is not between the excitement, due to the existence of potential difference in the charge movement, which is the local current. Its flow direction is: there is a positive charge outside the membrane has never excited to flow to the excitement section, the cell has a positive charge from the excited flow to the excitement section, the current direction is not excited to fiber membrane depolarization. When this current is strong enough to depolarize the segment to reach the threshold, a new nerve impulse - action potential is generated.
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological functions of minerals: 1. constitute the body of the material. (Such as calcium, phosphorus, magnesium is a bone, an important component of the teeth.) 2. Regulate the physiological function. (Minerals are often enzymes activators.) 3. Participate in the regulation of body fluid balance and maintain the body's acid-base balance.
Q:Why plasma osmotic pressure and protein, inorganic salt content
Plasma osmotic pressure is divided into crystalline osmotic pressure and colloid osmotic pressure.
Q:What is the difference between organic salt and inorganic salt?
Organic and inorganic chemistry are subdisciplines within chemistry. In organic chemistry, scientific study is concentrated towards carbon compounds and other carbon-based compounds such as hydrocarbons and their derivatives. Read more: www.differencebetween.net/science...
