Add one part clear household ammonia to 10 parts water. Start by applying the solution to the affected area, using a scrub brush or a clean cloth to gently scrub the stains. I had a tough hairspray buiildup on my bathroom floor. I mixed ammonia with hot water and was able to easily wipe away the buildup. No scrubbing needed! In this guide, I provide a list of cleaners that contain ammonia and offer recommendations for viable ammonia-free alternatives. Just add one cup of ammonia to a full load of laundry with your detergent. Then run a second rinse cycle to remove any lingering odours before drying your whites in the sun for some additional natural brightening. Clean mildew off unfinished and painted wooden patio furniture and picnic tables with a mixture of 1 cup ammonia, ½ cup vinegar, ¼ cup baking soda, and 1 gallon water. Rinse off thoroughly and use an old terry cloth towel to absorb excess moisture.

Due to its attributes, being liquid at ambient temperature under its own vapour pressure and having high volumetric and gravimetric energy density, ammonia is considered a suitable carrier for hydrogen, [115] and may be cheaper than direct transport of liquid hydrogen. [116] Refrigeration – R717 [ edit ] The fermentation of urine by bacteria produces a solution of ammonia; hence fermented urine was used in Classical Antiquity to wash cloth and clothing, to remove hair from hides in preparation for tanning, to serve as a mordant in dying cloth, and to remove rust from iron. [49] It was also used by ancient dentists to wash teeth. [50] [51] [52] Swallowing a cleaning product that contains ammonia can burn the mouth, throat, and stomach and cause severe abdominal pain. If a cleaning product containing ammonia is accidentally ingested, read the product label for safety instructions, or call the National Poison Control Center at 1-800-222-1222, and be sure to have the label from the cleaning product in hand.The hazards of ammonia solutions depend on the concentration: 'dilute' ammonia solutions are usually 5–10% by weight (<5.62mol/L); 'concentrated' solutions are usually prepared at >25% by weight. A 25% (by weight) solution has a density of 0.907 g/cm 3, and a solution that has a lower density will be more concentrated. The European Union classification of ammonia solutions is given in the table. Liquid ammonia is used for treatment of cotton materials, giving properties like mercerisation, using alkalis. In particular, it is used for prewashing of wool. [123] Lifting gas [ edit ]

In the US as of 2019 [update], approximately 88% of ammonia was used as fertilisers either as its salts, solutions or anhydrously. [66] When applied to soil, it helps provide increased yields of crops such as maize and wheat. [67] 30% of agricultural nitrogen applied in the US is in the form of anhydrous ammonia, and worldwide, 110million tonnes are applied each year. [68] Precursor to nitrogenous compounds [ edit ]The ammonia molecule has a trigonal pyramidal shape as predicted by the valence shell electron pair repulsion theory (VSEPR theory) with an experimentally determined bond angle of 106.7°. [29] The central nitrogen atom has five outer electrons with an additional electron from each hydrogen atom. This gives a total of eight electrons, or four electron pairs that are arranged tetrahedrally. Three of these electron pairs are used as bond pairs, which leaves one lone pair of electrons. The lone pair repels more strongly than bond pairs; therefore, the bond angle is not 109.5°, as expected for a regular tetrahedral arrangement, but 106.8°. [29] This shape gives the molecule a dipole moment and makes it polar. The molecule's polarity, and especially its ability to form hydrogen bonds, makes ammonia highly miscible with water. The lone pair makes ammonia a base, a proton acceptor. Ammonia is moderately basic; a 1.0 M aqueous solution has a pH of 11.6, and if a strong acid is added to such a solution until the solution is neutral ( pH = 7), 99.4% of the ammonia molecules are protonated. Temperature and salinity also affect the proportion of ammonium [NH 4] +. The latter has the shape of a regular tetrahedron and is isoelectronic with methane. Let the solution sit for a few hours or, if you can, overnight. This will allow the ammonia to break down the grease and grime.
