Appearance: white powder, 325-3000 mesh

Application: It can be used as the raw materials or fillers in oil paint,ink,plastic,rubber and battery ,the Surface smear medicament of the Printing paper and copper board , and sizing agent for textile industry. As clarifying agent,it can play a role of anti-foaming and increase the glossy of glass products. It also can be used as an anti-radiation protective wall materials. In addition,it’s widely used in pottery , enamel, spices and paints, etc. What’s more, it can be used as the raw materials to produce other barium salts.

Q: How does inorganic salts maintain osmotic pressure and pH: PH ~ inorganic salts of carbonates bicarbonate, hydrogen phosphate / dihydrogen phosphate, can help regulate the pH value of the internal environment, even if the external environment Zoumu changes, the environment will not change too fast, there will be a Buffer room

Q: Is the conduction of excitement on neurons related to inorganic salts?: Neurons, also known as nerve cells, constitute the basic unit of the nervous system structure and function.

Q: People do not eat salt tears with no inorganic salt: I suddenly think of a science program that found a place a strange person, never drink water, then a variety of surprises. Finally, the scientist came out to explain that he can get the daily water needed from the food.

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: The human body does not intake of minerals can be? Lack of minerals on the human body what kind of harm?: Body weight: 96% is organic matter and moisture, 4% for the inorganic elements of the body about 50 kinds of minerals, in these inorganic elements, has been found in about 20 elements constitute the body tissue, to maintain physiological function, Biochemical metabolism necessary, in addition to C, H, O, N mainly in the form of organic compounds, the rest are known as inorganic salts or minerals can be divided into constant elements and trace elements two categories.

Q: I had asked a similar question on GC operation last week, but for different kinds of compounds.For my biochem research project at school, I&#39;m testing the ability of a species of bacteria to biodegrade alcohols found in gasoline (methanol, ethanol, isopropyl, tert-butyl and cyclohexanol). The bacteria is growing in a solution of minute amounts of alcohols and Mineral Medium, which is basically just water and dissolved inorganic salts (CaCl2, KH2PO4, NH4NO3 and MgSO4).I know GC&#39;s are primarily used to separate organic mixtures. Can a GC separate organic compounds dissolved in salt water? Is it safe to put salt water in a GC? Or would I have to do an extraction to separate the alcohols and run the organic extract through the GC?: Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.

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.

Q: As if there are two kinds of nitrogen, phosphorus and potassium, hoping to get answers and explain their respective roles: Only 70 kinds of chemical elements can be detected in plants, but only 16 kinds of essential nutrient elements are needed for the growth and development of internationally recognized higher plants. They are carbon (C), hydrogen (H), oxygen (O), nitrogen (Fe), magnesium (Mg), sulfur (S), iron (Fe), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo) and chlorine (C1), which can be divided into large nutrient elements, medium nutrient elements and micronutrient elements according to their requirements, such as carbon, hydrogen, oxygen and nitrogen Phosphorus, potassium, copper, zinc, molybdenum and chlorine.Now there are scholars that nickel (Ni) is the first 17 kinds of essential nutrients.

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: RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?: Dr. Henry A. Schroeder, the world's mineral authority, says that the minerals required by the human body are present in the water, meaning nothing more than those that exist in food.
