Concentrated sulfuric acid properties of concentrated sulfuric acid dehydration dehydration means removing non-free state water molecules or hydrogen atomic ratio in accordance with the water off the organic process for the formation of hydrogen and oxygen elements. To sulfuric acid, the dehydration of concentrated sulfuric acid nature, rather than the nature of sulfuric acid, concentrated sulfuric acid has a strong dehydration and dehydration, dehydration, according to the composition ratio of water off. Substance was dehydrated concentrated sulfuric acid process is a chemical change, reaction, concentrated sulfuric acid by water molecules than the original number of hydroxide (2: 1) to win by dehydrate the hydrogen atom and an oxygen atom or off the water of crystallization of the non-free state , such as copper sulfate pentahydrate (CuSO4 · 5H2O). Concentrated sulfuric acid etch through the material quickly towels can be concentrated sulfuric acid dehydration is usually hydrogen, oxygen organic matter, in which sugar, wood, paper and organic cotton and other materials, the young man became dehydrated carbon black, a process called carbonization. A typical reaction charring sucrose black bread. Placed in a 200mL beaker, 20g sugar, add a few drops of water, add appropriate amount of water, and mix well. Then added 15mL mass fraction of 98% concentrated sulfuric acid plant in Shijiazhuang, stir quickly. Experimental phenomena observed. You can see the sugar gradually darken, volume expansion sulfuric acid plant in Suzhou, forming porous sponge-like carbon Shanghai sulfuric acid plant, an exothermic reaction, can smell the pungent gas. C12H22O11 ==== 12C + 11H2O simultaneous reaction of carbon with concentrated sulfuric acid: C + 2H2SO4 (concentrated) presence ==== CO2 ↑ + 2SO2 ↑ + 2H2O sulfuric acid rain earth containing sulfuric acid, acid rain, sulfur dioxide (SO2) reaction with water in the atmosphere to produce sulfurous acid (H2SO3), sulfurous acid has been oxidized by oxygen in the atmosphere to form sulfuric acid, with the rain falling to the ground, causing the formation of acidic soils. Improved acid soil is usually neutralized with an alkaline substance. In nature, many sulfur-containing minerals, such as iron sulfide after the oxidation reaction to form sulfuric acid, the liquid formed is highly acidic, the metal residues can be oxidized, releasing toxic gases. Venus sulfuric acid can be found in the upper atmosphere of Venus. This mainly comes from the photochemical sun on sulfur dioxide, carbon dioxide and water. Wavelengths shorter than 160nm ultraviolet photons can photolysis of carbon dioxide, carbon monoxide and atomic oxygen so that it changes. Atomic oxygen is very active within the chain, it reacts with sulfur dioxide into sulfur trioxide. Further sulfur trioxide reacts with water to produce sulfuric acid release. Sulfuric acid in the atmosphere of Venus is higher colder liquid, this layer thick, about 45 to 70 kilometers away from the surface of the planet sulfuric acid cloud cover the entire surface of the planet. This layer of the atmosphere continue to release acid rain. Venus, the formation of sulfuric acid in the continuous cycle. When higher from the atmosphere cooler regions fell to a lower sulfuric acid is evaporated in hot areas, the water content and the concentration of less is more and more high. When the temperature reaches 300 ℃, sulfuric acid begins to decompose to sulfur trioxide and water, are the product gas. Trioxide very active and decomposition of sulfur dioxide and atomic oxygen, atomic oxygen and then make it into carbon dioxide carbon monoxide oxidation sulfuric acid plant, sulfur dioxide, and water will rise from the middle to the upper atmosphere, they react with sulfuric acid to re-release the entire process and cycle again. Europa by the Galileo spacecraft images show came, sulfuric acid may also appear in one of the satellites of Jupiter - Europa, but the details still controversial.
