Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula N H 3.A stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell.
Table data (above) obtained from CRC Handbook of Chemistry and Physics 44th ed. The (s) notation indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid.
Because aqueous ammonia is a gas dissolved in water, as the water evaporates from a surface, the gas evaporates also, leaving the surface streak-free. Its most common uses are to clean glass, [10] porcelain, and stainless steel. It is good at removing grease and is found in products for cleaning ovens and for soaking items to loosen baked-on grime.
2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to retain its level of free acid.
Using rubber pumps, air (acting as gas-carrier) is injected in the gas-washing tubes causing the streams of ammonia and hydrogen chloride in air to collide and react giving the solid product, ammonium chloride. It is a product of the Solvay process used to produce sodium carbonate: [3] CO 2 + 2 NH 3 + 2 NaCl + H 2 O → 2 NH 4 Cl + Na 2 CO 3
It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia ( NH 3 ). Ammonium is also a general name for positively charged (protonated) substituted amines and quaternary ammonium cations ( [NR 4 ] + ), where one or more hydrogen atoms are ...
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
