4. Nickel tube use
Nickel tube use: alkali industry. Chlor-alkali chemical industry and production of organic chlorides. Food processing industry. High temperature halogen and salt corrosive environment. Electronic instrument parts. Water treatment. All kinds of alkali resistant equipment
Nickel is insoluble in water and forms a dense oxide film on the surface of the humid air at room temperature, which can prevent the continued oxidation of the main metal. It can dissolve slowly in dilute acid and release hydrogen gas to produce green n-divalent nickel ion Ni2+. Strong alkali resistance. Nickel can be burned in pure oxygen, producing a brilliant white glow. Nickel can also be burned in chlorine and fluorine. The oxidizing solution, including nitric acid, does not react. Nickel is a moderate-strength reducing agent. Nickel is slowly corroded by hydrochloric acid, sulfuric acid, organic acid and alkaline solution. Nickel dissolves slowly in dilute nitric acid. Fuming nitric acid can passivate nickel surface and has corrosion resistance. Nickel, like platinum and palladium, can absorb a large amount of hydrogen during passivation. The smaller the particle size, the greater the absorption. The important salts of nickel are nickel sulfate and nickel chloride. Nickel nitrate is also commonly used in the laboratory, with crystalline water, the chemical formula is Ni(NO3)2·6H2O, green transparent particles, easy to absorb water vapor in the air. Similar to iron and cobalt, it is stable to water and air at room temperature and can resist alkaline corrosion, so nickel can be used in the laboratory
