Sulfate [properties] 1. to master the college entrance test of concentrated sulfuric acid (water absorption, dehydration, oxidation) college entrance test 2. master test method of sulfate ion sulfate 3. common understanding (calcium sulfate, barium sulfate)] [] points of knowledge points of knowledge. The structure of sulphuric acid two. 1. properties of physical properties of pure sulfuric acid is a water miscible with arbitrary ratio, a large amount of heat when dissolved like color. Belong to the body, volatile acid, soluble in water, can Diluting concentrated sulfuric acid or concentrated sulfuric acid mixed with other liquids steps:. 2. chemical properties: 1 - two yuan with dilute sulfuric acid cause The catalyst of sulfuric acid in the water absorption dehydration important -- an important catalyst - sulfuric acid - sulfuric acid The concentration of sulfuric acid as catalyst Dilute sulfuric acid The oxidation of (Cu, Zn, and passivation, Fe, C, S, H2S, HBr, HI and other reducing substances reaction) H2SO4 + C = H2SO4 + Cu = summary: not with concentrated sulfuric acid drying gas with the sulfonation reaction of C6H6 + HO - SO3H - C6H5 - SO3H + H2O, the reaction belongs to One H2SO4 + HBr =; . (under certain conditions, can dilute sulfuric acid and copper?). Reaction. Test three: using.SO42 ion liquid, such as four common sulfate. CaSO4 - 2H2O 2CaSO4 - H2O sulfate BaSO4 ZnSO4 - 7H2O Na2SO4 - 10H2O FeSO4 - 7H2O CuSO4 - 5H2O (students) gypsum plaster alum mirabilite barite Hao uses business model or brochantite Chalcanthite melanterite; plaster bandage; adjust the cement hardening time barium meal; white pigment astringent, antiseptic, mordant, white pigment laxative agent, pulp and paper industry
