Sulfuric acid is one of the important products in the basic chemical industry. It is not only used as a raw material for many chemical products, but also widely used in other sectors of the national economy.
2. Selenic acid. Selenic acid is a strong acid, which is basically as acidic as sulfuric acid. Concentrated selenic acid is also dehydrating and absorbent, but weaker than concentrated sulfuric acid.
Slightly more oxidizing than nitric acid.
Much stronger than sulfuric acid.
3. Metasilicic acid.
Has a softening effect on blood vessels on heart disease.
High blood pressure has some efficacy.
4. Adipic acid.
It is easy to form calcium oxalate with calcium-containing substances, and calcium oxalate is the most common kidney stone.

Anonymous users2024-02-15Dibasic acids refer to the most commonly used diacids in synthetic alkyd resins are phthalic acid (phthalic anhydride is commonly used) and isophthalic acid. Because isophthalic acid does not undergo intermolecular cyclization, it can be prepared from alkyd resins with high molecular weight and high viscosity.
Compared with alkyd resins synthesized from phthalic anhydride, dibasic acids have the characteristics of fast dyeing, good flexibility, and good heat and acid resistance. However, isophthalic acid has a high melting point and takes a long time and high temperature to dissolve in the reaction mixture, so it is easy to lead to dimerization and its side reactions with polyols.

Note: Nitric acid (HNO3) is a monobasic acid!
Organic diacids: acids that contain two carboxyl groups (e.g., adipic acid).

Anonymous users2024-02-13Dibasic acids are: sulfuric acid, selenic acid, metasilicic acid.
hydrosulfuric acid, etc. Sulfuric acid (chemical formula: H2SO4), the most important oxygenated acid of sulfur. Anhydrous sulfuric acid is a colorless oily liquid, when crystallized, it is usually used in various concentrations of aqueous solutions, using the tower method and contact method.
Diacids are acids that ionize one of these acid molecules to produce two hydrogen ions.
of acids. Cation on ionization.
Substances (except water) that are all hydrogen ions are acids. According to the number of hydrogen ions ionized by each acid molecule, it is called several distraction acids, such as cha or mono acid, dibasic acid, triary acid, etc.

Anonymous users2024-02-11Question 1: What are the local areas of monobasic acids and what are the dibasic acids? Monoacids: HCl, Hi, HBR...Wear.
Dibasic acids: H2CO3, H2SO4...
Question 2: What are dibasic acids and monoacids and what is the difference between them? Monoacids usually refer to acids that may emit a proton (H) in a molecule.
Such as hydrochloric acid (HCL), nitric acid (HNO3) in inorganic acids, etc. In organic compounds, it mainly refers to carboxylic acids containing one carboxyl group per molecule, such as formic acid (HCOOH), acetic acid (CH3COOH), benzoic acid (C6H5COOH), etc. Although these compounds do not have just one hydrogen atom in them, they also have only one ion.
Inorganic diacids: acids (including oxygenated acids and anaerobic acids, such as sulfuric acid, hydrosulfuric acid, etc.) that can ionize two hydrogen ions per molecule in water
Organic diacids: acids (e.g. adipic acid) that contain two carboxyl groups
The difference is whether a molecule may emit one proton or two protons (hydrogen ions).
Question 3: What are the characteristics of dibasic acids? Such as sulfuric acid, carbonic acid, etc. are dibasic acids. Their salts are normal salts and acid salts: NaHCO3, NA2CO3
It's easy to understand.
It reacts with both alkali and acid.
Note that sodium bisulfate is special, he is completely ionized in aqueous solution to produce sulfate, hydrogen ions, sodium ions.
Binary options, also known as digital options, are a simplified financial instrument. Binary options only consider the direction of the underlying asset, that is, bullish or bearish, while investors in traditional financial instruments such as foreign exchange need to consider the direction and the range of ups and downs at the same time, so binary options are simplified financial instruments. The returns and risks of binary options are pre-fixed, and the benefits are determined only by whether the underlying asset** meets the predetermined conditions. >>>More
No, what you can see is not all fake, all the regular foreign transactions are traded, but you will definitely not be able to touch the domestic over-the-counter market, but it is only suitable for institutions.
