- Q: What is white alkali?
- Sodium carbonate [497-19-8] (Na2CO3), molecular weight 105.99. Chemical purity of more than 99.5% (mass fraction), also known as soda ash, but the classification belongs to the salt, does not belong to the base. International trade, also known as soda or alkaline ash. It is an important organic chemical raw materials, mainly for the production of flat glass, glass products and ceramic glaze. But also widely used in life washing, acid and food processing.
- Q: Organic chemistry extraction lab. If the KBr wasn't there I would just add HCl to protonate the NH2, but I'm not sure if that will affect the KBr or the carbon chain. Both of these are in an aqueous phase.
- The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.
- Q: Oxide and organic peroxide signs
- Broad oxide (oxide) refers to the oxygen element and another chemical composition of the binary compounds, such as carbon dioxide (CO?), Calcium oxide (CaO) and so on. But the combination of oxygen and electronegativity with greater fluoride is generally referred to as fluoride rather than oxide.
- Q: What is the difference between chemical monomer and elemental
- And the element is composed of the same element of pure matter. An element is called a free state of an element in the presence of an element. In general, the nature of the element is closely related to the nature of its element. For example, the metal properties of many metals are obvious, then their elemental reducibility is very strong. Different elements of the element, the nature of the differences reflected in the structure of the most prominent. In contrast to elemental matter, a substance consisting of multiple elements is called a compound
- Q: Salt is not a kind of inorganic salt
- Salt chemical name is called "sodium chloride", chemical symbol: NaCl
- Q: ATP components are not inorganic salts
- Of course not pulling, because ATP is decomposed by glucose to get energy that is ATP and salt and water.
- 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 is alkali?
- What is the alkali is the ionic compound, the ionization of the anion is hydroxide (OH-), in fact, the oxygen ion acid root (which can compare sulfur and sulfur), and the anion contains only hydroxide. (Such as LiOH, NaOH, NH3 · H2O) soluble in water, alkaline earth metal ions formed in the periodic table from top to bottom gradually soluble [Be (OH) 2, the alkali metal ions or alkali ions, Mg (OH) 2 is insoluble, Ca (OH) 2, Sr (OH) 2 is slightly soluble, and Ba (OH) 2, Ra (OH) 2 is easily soluble, and other bases are in addition to TlOH and Tl (OH) Is difficult to dissolve alkali and acid metathesis reaction is also known as neutralization reaction, that is, H + + OH- == H2O
- Q: What is the alkaline powder? Baking soda? Sodium carbonate or something else?
- Baking soda is very easy to absorb the air of the air, so when not in use when the best way to retract, such as sealed cans or folder chain or milk powder cans. Use, you can use a commercially available pepper to retract, but not Add the lid, pepper cans of the hole is very easy to sprinkle the small soda.There is no pepper cans, you can also have a hole in the cloth, such as not the yarn quality curtains, mosquito nets, etc., tied tied to the general bottle, It is easy to pour out to use.If you just want a simple moisture and deodorant, you can put the small soda in the old cotton socks, and then sealed with a rope, and then any use can be
