(1) In agriculture and gardening, magnesium sulphate is used to correct magnesium deficiency in soil.

It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, and peppers.

 The advantage of magnesium sulphate over

other magnesium soil amendments is its high solubility.
(2) It is used as magnesium fertilizer in agriculture and also used as feed additives.
(3) used as the weight additive for cotton, silk, filling for wood products, and also for the manufacture of

porcelain paint and material of fireproof .
(4) In microbial industry, it is used as the components of growth media, additives of brewing to be the nutrition

sources of fermentation. It is used to enhance the heat endurability as the filling agent in tanning industry.
(5) In light industry, it is used in production of the fresh yeast MSG and the stabilizer of the calcium hydrogen

phosphate for the toothpaste production and the congealing agents for cement, as well as used in pulp and textile

industry, and other industries.

Q:Is urea an inorganic salt?
Is not organic matter ah inorganic salts are present in the body and food minerals in the mineral, composed of organic matter and inorganic synthesis of the human body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. More (> 5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven; daily dietary requirements are more than 100mg, known as constant elements. Other low content, with the modern analysis of technological progress Iron, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements were found by atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods. But also the human body is necessary, the daily dietary requirements for the amount of μg ~ mg called trace elements.
Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
to maintain the body's acid-base balance
Q:How too much to eat too much inorganic salt
Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.
Q:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?
Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.
Q:What are the main physiological functions of inorganic salts?
o maintain the body acid and alkali balance and osmotic pressur
Q:Which solvents have some solubility in inorganic salts
A wide variety of dyes, dissolved complex. The original dyes are organic, but some salt, some metal complexes, some of the larger molecules of the fused ring compounds, some polymer heterocyclic compounds, in some common organic solvents in the solubility is better than disperse dyes Raw dyes and oil-soluble dyes (this is actually the raw material of solvent pigments, strictly speaking, not dyes). There are basically additives in the finished dyes, such as direct dyes, acid dyes, reactive dyes, cationic dyes and other water-soluble dyes will be added inorganic salts, disperse dyes, reducing dyes will be added sulfonate sodium dispersant. In addition, the dye and other chemical products, their purity requirements are generally very low, will allow the presence of certain insoluble impurities. So the organic solvent can not be completely dissolved dye products really is very common or even a normal phenomenon.
Q:The inorganic portion of bone tissue is made of what complex mineral salt ?
hydroxyapatite - Ca10(PO4)6.(OH)2 - which covers the calcium and phosphorous that are needed for bone development And just so you know, plants don't have "bones" - your question was posted in Botany.
Q:TRUE OR FALSE: the addition of salts to water will always increase the surface tension of water. explain.?
False. Although inorganic salts will increase surface tension of the water by increasing the attractive forces between water molecules on the surface, organic salts will typically (always?) decrease the surface tension.
Q:People lack the inorganic salt will be what disease
Calcium deficiency can lead to osteomalacia, osteoporosis, etc., can also lead to convulsions.
Q:Calcium is not an inorganic salt
Calcium salt is determined whether it is inorganic salt depends on its acid, if it is organic acid synthesis of calcium salt is organic salt, if it is inorganic acid synthesis of calcium salt is inorganic salt. The main basis for determining the inorganic salts is whether or not organic reactants are involved in the formation process.
