The hazards of ammonia solutions depend on the concentration: 'dilute' ammonia solutions are usually 5–10% by weight (< 5.62 mol/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 table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in kPa. The third column is the density of the liquid phase. The fourth column is the density of the vapor.
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
The truck was carrying about 7,500 gallons of anhydrous ammonia at the time, according to the Illinois Environmental Protection Agency. The agency said early estimates indicate more than half ...
The proposed development of a green ammonia plant near Robstown may call for as much as 5.5 million gallons of water per day for production.
A tanker carrying anhydrous ammonia, a poisonous gas, overturned and began leaking on Friday night in Illinois, killing five
Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [23] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [24] [25] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...
At standard mean sea level it specifies a temperature of 15 °C (59 °F), pressure of 101,325 pascals (14.6959 psi) (1 atm), and a density of 1.2250 kilograms per cubic meter (0.07647 lb/cu ft). It also specifies a temperature lapse rate of −6.5 °C (−11.7 °F) per km (approximately −2 °C (−3.6 °F) per 1,000 ft).
