The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in k Pa . The third column is the density of the liquid phase.
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 −
Ammonia is also directly toxic to fish and as the amount of ammonia increases, the more that accumulates in their bodies and it becomes harder to for the animals to remove it from their bodies. Freshwaters tend to have a wide range of pH values from 6.5 to 9. [ 25 ]
Ammonia is used in numerous different industrial applications requiring carbon or stainless steel storage vessels. Ammonia with at least 0.2% by weight water content is not corrosive to carbon steel. NH 3 carbon steel construction storage tanks with 0.2% by weight or more of water could last more than 50 years in service. [141]
Typically, after a system has stabilized ammonia levels range from 0.25 to .50 ppm; nitrite levels range from 0.0 to 0.25 ppm, and nitrate levels range from 5 to 150 ppm. [citation needed] During system startup, systems take several weeks to begin the nitrification process. [36]
Daphnia magna, a good example of a primary member of the food chain, is a small planktonic crustacean, about 0.5 mm (0.020 in) in length, having an LD50 of about 10,000 ppm TDS for a 96-hour exposure. [11] Spawning fishes and juveniles appear to be more sensitive to high TDS levels.
An ammonia leak at a commercial food preparation facility in Virginia sent 33 people to the hospital, authorities said Thursday. The leak at the Cuisine Solutions plant in Sterling on Wednesday ...
The toxicity of ammonia is dependent on both pH and temperature and an added complexity is the buffering effect of the blood/water interface across the gill membrane which masks any additional toxicity over about pH 8.0. The management of river chemistry to avoid ecological damage is particularly difficult in the case of ammonia as a wide range ...
