chemical properties of ammonia

Post 1 of 14

Ammonia is a chemical compound that has the formula NH3, being made out of one nitrogen atom and three hydrogen atoms.The molar mass of NH3 (ammonia) is 17.031 g per mole. Catalyst used – (Fe 2 O 3).It only speeds up the reaction, doesn’t changes its yield. Moreover, it readily dissolves in water in an exothermic reaction, to form an aqueous ammonia solution that we … Reaction with air/oxygen:Ammonia does not burn in air. Conditions for optimum yield of ammonia : The reaction is exothermic, reversible and occurs with a decrease in volume. Ammonia is lighter than air with a density of 0.769 kg/m3 at STP. The physical and chemical properties of ammonia are presented in Table 4-2. If values are given for liquid ammonia at ambient temperature, the ammonia is pressurized above 1 atm. So, Le- Chatelier’s principle … Ammonia is a colorless gas with a chemical formula NH 3. It is a weak base that combines with numerous acids to form ammonium salts that are important in chemical industries. Ammonia in solution is widely available, and it is often referred to as ammonium hydroxide and has been also historically referred to as “spirit of hartshorn” (Windholz 1983). Ammonia is a colourless gas with a characteristic pungent smell and hazardous in its concentrated form.. Chemical, physical and thermal properties of Ammonia, NH 3: Values at 25 o C /77 o F / 298 K and 1 atm., if not other temperature and pressure given. Structural, Chemical and Physical Properties of Ammonia Physical Properties Property Value or Detail Molecular Mass 17.03 g/mol Colour Colourless Odour Sharp, Intensely Irritating Physical State Gas (at room temperature) Melting Point -77.7°C Boiling Point -33.35°C Flash Point 11°C Decomposition Point 500°C Density (Gas) 0.7710g/L Density (Liquid) 0.6818g/L … What is Ammonia? Incompatible with many materials including silver and gold salts, halogens, alkali metals, nitrogen trichloride, potassium chlorate, chromyl chloride, oxygen halides, acid vapors, azides, ethylene oxide, picric acid and many other chemicals. Ammonia in water solution is called aqua ammonia or ammonium hydroxide. Properties of Ammonia 1. The resulting nitrogen oxides will support combustion, even in the absence of other oxygen.The resulting heat and pressure from the decomposition of ammonium nitrate may build up if the reaction takes place in a confined space and the heat and gases created are not able to dissipate. It is a reaversible chemical reaction doesn’t go to 100% completion. Ammonia in solution is widely available, and it is often referred to as ammonium hydroxide and has been also historically referred to as “spirit of hartshorn” (Windholz 1983). In its concentrated form, it is dangerous and caustic. At 68°F, about 700 volumes of vapor can be dissolved in one volume of water to make a solution containing 34 percent ammonia by weight. Action of heat: Ammonia is heated above 500°C decomposes into its elements. The chemical properties of ammonia include ammonia having high stability, being combustible in air, and forming nitric oxide when combined with a platinum-rhodium catalyst at approximately 800°C. Conditions : Temperature of 450C. Ammonia as a Fertilizer: Plants need nitrogen as on eof components for growth and ammonium fertilizers contain Nitrogen for that. Home Chemical Properties: Ammonia (NH3) Ammonia is more than that scalding chemical that you use to clean your house. The physical and chemical properties of ammonia are presented in Table 4-2. Also included are some chemical and physical properties of ammonia in solution. It consists of hydrogen and nitrogen. When a mixture of nitrogen and hydrogen gas in the ratio 1:3 by volume is heated at a temperature of 450-500 0 C and 200-900 atmospheric pressure in the presence of iron as catalyst and molybdenum as promoter, ammonia gas is produced.. In its aqueous form, it is called ammonium hydroxide. Pressure of 200 atm. . Also included are some chemical and physical properties of ammonia in solution. Decomposition creates toxic gases containing ammonia and nitrogen oxides. This inorganic compound has a pungent smell. Mixing of ammonia with several chemicals can cause severe fire hazards and/or explosions. Chemical Properties of Ammonia. Chemical Properties: Anhydrous ammonia is easily absorbed by water.
