Inorganic acids, also known as mineral
acids, are a general term for acids in inorganic compounds. Inorganic acids, in
general, are inorganic compounds that can dissociate hydrogen ions. A compound
consisting of hydrogen and a non-metallic element or a group thereof. For
example, hydrochloric acid (HCl), nitric acid (HNO3), boric acid (H3BO3),
sulfuric acid (H2SO4), carbonic acid (H2CO3), phosphoric acid (H3PO4) and the
like.
According to the composition, inorganic
acids can be divided into oxygen-containing acids, anaerobic acids, complex
acids, mixed acids, superacids, etc., according to the degree of dissociation,
can be divided into strong acids and weak acids, but also according to the
number of hydrogen ions in the molecule can be ionized into monobasic acids,
dibasic acids and polyacids.
Inorganic acids are mostly used to provide
hydrogen ions.
Inorganic acids are divided into inorganic hydrogenic acids and inorganic oxygenated acids according to their composition.

The reason is that "it can be seen that subsidizing public transport is a relatively clear idea for the country."
On December 27, BYD Auto Proving Ground and its parts and components base officially started construction in Shaoguan. This is the last project started by BYD Auto in 2009. This piece of (Eastern) Guanlan (Guan) Industrial Park is still a muddy wilderness, but in the face of the enthusiasm of the local government, Wang Chuanfu immediately stated that the original three-year production value will be more than 1 billion yuan, to 3 billion yuan the above.
Wang Chuanfu said that the test site is expected to invest 700 million. After completion, it can provide international standards for automotive testing, R&D, testing, and regulatory verification services for China and the Asia-Pacific region. The auto parts production base is expected to invest 800 million yuan, mainly producing automotive secondary and tertiary assembly components. Shaoguan base is located in the middle of BYD Shenzhen and Changsha.
Wang Chuanfu also announced that BYD's car production and sales volume has exceeded 440,000 units in 2009, a year-on-year increase of 158%. It is 110% higher than the average growth rate of the industry. However, he did not mention BYD's sales data and plans for new energy vehicles in 2009 and next year.
In fact, BYD Auto's two other major new energy businesses (DM models and pure electric vehicles) have attracted considerable attention. In the "New Energy Recommended Catalogue" issued by the Ministry of Industry and Information Technology, BYD's dual-mode electric car is the first and only car that has been recommended. In the middle of the year, Wang Jianjun, deputy general manager of BYD Automobile, disclosed that the fourth quarter of F3DM, which faces only the group and the government, will begin to be officially sold to the individual market in Shenzhen, because the Shenzhen government will soon introduce relevant subsidy policies. However, at the end of the year, no progress has been seen.
In a recent briefing between BYD Auto and the media, Wang Jianjun once again disclosed that with regard to BYD new energy vehicles next year, Changsha’s bus base may be officially sold before F3DM in the Mainland, and F3DM, which focuses on the individual market, will continue to Road show. The reason is that "it can be seen that the subsidy to public transportation is a relatively clear idea for the country."
In May this year, the Ministry of Finance issued the “Circular on Launching Pilot Programs for Energy Conservation and New Energy Vehicle Demonstration and Promotion†and pointed out that pilot projects of energy conservation and new energy vehicles demonstration and promotion will be carried out in 13 cities, and the use of fiscal policies will encourage public transport and leasing. Public service, public service, environmental sanitation, postal services, and other public service sectors have taken the lead in promoting the use of energy-saving and new energy vehicles, and subsidizing the promotion and use of units for the purchase of energy-saving and new energy vehicles. Among them, the central government focuses on granting subsidies for the purchase of energy-saving and new energy vehicles, and the local finance focuses on subsidies for the construction and maintenance of related auxiliary facilities.
The Ministry of Finance’s subsidy for hybrid vehicles is divided into five levels of subsidy according to the fuel saving rate, with a maximum subsidy of RMB 50,000 for each vehicle, RMB 60,000 for each subsidy for electric vehicles, and RMB 250,000 for fuel cell vehicles.
There are separate standards for bus buses of more than ten meters in length, of which hybrid vehicles are classified into lead-acid batteries and nickel-metal hydride batteries and lithium-ion batteries. The maximum subsidies are 80,000 yuan per vehicle and 420,000 yuan per vehicle. The subsidy standard for electric vehicles is 500,000 yuan per vehicle; the subsidy standard for fuel cell vehicles is 600,000 yuan per vehicle.
"Up to 500,000 yuan / vehicle subsidies for pure electric buses, at least we can not lose." Wang Jianjun said.
According to an agreement signed between BYD Auto and Hunan Environmental Protection Technology Industrial Park, BYD's acquisition of US buses as a whole for electric buses and chassis production will reinvest no less than 3 billion yuan in the park and build a new energy vehicle with a scale of 4 square kilometers. The production base is expected to have an output value of at least 30 billion yuan within three years of production. The BYD Changsha plant is currently under intense construction. Plants such as assembly and welding equipment have been excavated. The first phase of the project will be completed next year and BYD electric buses will be put into production. After the new energy auto base is built, BYD will assume the production capacity of 5,000 B6 and B9 pure electric buses and 10,000 chassis.
The general formula of hydroic acid is MHm, the structure is relatively simple, it is some hydride of the periodic table, the group of elements. They are in an aqueous solution, can give protons, appear acidic.
For hydrogenic acid, the higher the electronegativity of its central atom M, the stronger the ability to attract electrons, the easier it is to give protons, and the stronger its acidity. For the same cycle, as the family of M changes, the electronegativity of M gradually increases in the sequence, and the acidity of its corresponding MHm is gradually enhanced.
Contains grade acids
The general formula for oxygenated acids is XOm(OH)n, where X is the central atom.
The structure of the oxygenated acid is more complex than that of the hydroacid, and its structure is related to the number of cycles in which the central atom X is located. In the second cycle, H3BO3,H2CO3, HNO3, and BO32-, CO32-,NO3- are planar structures that contain out-of-bound π bonds.
