2. Main Features of Soda Ash：

White powdered crystal, true specific gravity 2.533(20°C), easily soluble in water, most lubility at 35.4 °C. On exposure to air it easily absorbs moisture, carbon dioxide, and gradually to form a cake.

Keep away from sunlight and moisture,store in well ventilated dry place.

Soda ash is one of the basic materials for chemical industry. Mainly used for metallurgy, glass, textile, dye printing, medicine, synthetic detergent, petroleum and food industry etc.

5.FAQ

Are you a factory or trading company?

----We are the import-export branch of the factory--CNBMGroup. There are production unit and sales unit in our Group. Production unit is only responsible for producing cargos. We are in charge of sales. Even there is a "trade" in our name,but actrually we are factories.

• What is the minimum order?

----One Metric Ton

• How can I get sample for testing?

----Kindly send us your address, we will send the sample to you.

• Where is your factory located? How can I visit the factory?

----Our factory located in Shandong, China. It is in the north of China as a sea-side city. It is one hour flight from Beijing.

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: I have been very confused, baking soda and edible alkali surface is the same thing? Tea in the consumption of baking soda is not become alkaline? Can drink? How to quickly become alkaline? In addition to more melon Fruit and vegetables outside: Edible alkali is steamed bread, used in the kitchen to do the point, generally have to use baking soda, can be used to point of the fluffy.

Q: bonded to an acid molecule called- such as potassium citrate?Thanks: all metals like potassium,sodium,iron,magnecium etc are minerals

Q: Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference: GB / T5009.4-2003 "Determination of ash in food" (a) the principle of a certain amount of samples after carbonization into the high temperature furnace burning, the organic matter is oxidized decomposition to carbon dioxide, nitrogen oxides and Water and other forms of escape, and inorganic substances to sulfate, phosphate, carbonate, chloride and other inorganic salts and metal oxide in the form of residual

Q: Chemical formula The longest inorganic salt: The longest can have a large number of atoms, I remember the teacher said is more than a hundred different atoms or groups

Q: Alkaline pool can breed what: In the future of adult fish sales process found that after long-distance transport, part of the fish surface congestion, affecting the survival rate of transport and marketing. This may be associated with the addition of fish oil in the larger amount, resulting in high fish fat, muscle softness. Suggested in the late breeding, should reduce or even stop the addition of fish oil, and should increase the water flow, stimulate the fish, to achieve the purpose of exercise to improve the survival rate of transport.

Q: How to isolate the effects of inorganic salts on enzyme solubility: The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.

Q: In order to prove that magnesium is an essential salt for soybean life, two soybean seedlings with the same growth status are taken, one of them is cultured in magnesium-containing culture medium and the other is cultured in (). A. Pure water B. Sand without sand. Water containing only magnesium. Media containing no magnesium: Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.

Q: Consult the science and engineering, chemical and biological experts, plants absorb inorganic salts and water, then the absorption of inorganic salts in what form is absorbed into the way, is absorbed in the way of ions or in the way of the compound, And then only in the body only ionized into the ion state exists in the body. Grateful: Of course it is ion

Q: What is the lack of inorganic salts for children?: Children in the rapid development of the physical stage of the body, zinc consumption is very large, add must keep up, eat more fish and eggs, but not excessive.
