NH₄0H molecular 85.05
ammonia solution of ammonia, a colorless strong irritating odor. More ammonia content, the smaller the density. General pa strong ammonia 0.91g/cm³ density, the concentration of about 28% (mass percentage). -77 ° C melting point. Able to dissolve in water, ethanol and ether. Compared with the acid to produce a thermonuclear reaction, a strong smell of stimulation. On human eyes, nose and damaged sensitive skin irritation. A corrosive. The most concentrated ammonia 0.88g/cm³ density, the concentration of 35.28% (mass percentage). The ammonia are both free of ammonia, a molecule of ammonia hydrate and ammonium ion, the main form of ammonia hydrate molecule is, in essence, ammonia and water supply to the distribution of hydrogen bond formation of the combination. Only a small portion of ammonia hydrate molecules into ionization ion and ammonium hydroxide ions, it significantly alkaline solution. 25 ° C, ammonia ionization constant of K = 1.8 × 10^-5. The ammonia absorption of carbon dioxide, ammonium bicarbonate production; Sulfur dioxide absorption, generation Asian ammonium sulfate or ammonium bisulphite. At room temperature ammonia can be Cl2, KMnO4-oxidants, such as oxidation. With the formation of acid ammonium salt. With Ag +, Cu2 +, Cr3 +, Zn2 + and other metal ions generated complexes. Ammonia can be used as a chemical reagent, fertilizers, detergents, disinfectants, medicines. Access to ammonia in the water system.
applications in agriculture can be used as fertilizer diluted. Inorganic industrial system for the election of various molysite. Wool, silk, dyeing industry for washing wool, wool fabric, fabric, dissolution and adjustment of the pH value, and as such help dyes. Industrial organic amine agent for the production of thermosetting phenolic resin catalyst. Medicine used to dilute the ammonia with respiratory and circulatory reflex stimulation, to treat collapsed and fainted, and medicine for skin irritation and antiseptic. Also used as a detergent and neutralizer, alkaloids leaching agent.
