what does ammonia do to metal?
532036
Ammonia corrosion can cause stress corrosion cracking in steels. This occurs when contaminants in the ammonia are brought into contact with the steel, a situation that commonly occurs with pressure vessels. Care must be taken to ensure that pressure vessels are not subjected to this type of corrosion.

Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at −33.3 °C (−27.94 °F), and freezes to white crystals at −77.7 °C (−107.86 °F).

Most ammonia-free cleaning agents make use of a gentle or mild soap, like baby soap, water, and a disinfecting agent, like alcohol. These are the three main components that will make up your ammonia-free, tint safe cleaner. ... Isopropyl Rubbing Alcohol (91% is preferred, but lower percentage is also OK)

Many corrosives attack and corrode metals. ... Common bases, such as sodium hydroxide and potassium hydroxide, can also attack some metals like aluminum, zinc, galvanized metal, and tin to produce hydrogen gas.

The process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. with ΔH=−92.4kJ/mol. The catalyst: The catalyst is actually slightly more complicated than pure iron.

At low levels, ammonia burns the gills of your fish, placing them under incredible stress. As ammonia levels rise, it damages the brain and organs of your fish, until they eventually die. This process is known as nitrate poisoning.

Ammonia–at high temperature has high potential for nitriding metals. ... Condensed ammonia is a corrodent, and in anhydrous state it can cause stress-corrosion cracking of stressed carbon steels or high-strength, low-alloy steels. Hydrogen–in itself not corrosive but can lead to blistering and embrit- tlement of steel.

Except for Be, all the alkaline earth metals react with N2 to form nitrides, and all react with carbon and hydrogen to form carbides and hydrides. Alkaline earth metals dissolve in liquid ammonia to give solutions that contain two solvated electrons per metal atom.

Ammonia has a very strong odor that is irritating and that you can smell when it is in the air at a level higher than 5 ppm. Therefore, you will probably smell ammonia before you are exposed to a concentration that may harm you.

At room temperature, ammonia is a colourless, highly irritating gas with a pungent odour. In pure form, it is known as anhydrous ammonia and readily absorbs moisture. Corrosive. NH3 gas is easily compressed and forms a clear liquid under pressure.

Unlike many weed killers, however, ammonia is not selective and will kill any plant it comes into contact with. Thus, if you spray it on weeds in your lawn, it will not only kill the weeds but the grass that grows around it. Ammonia kills the plant by attacking its roots as well as its top growth.

Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals. It is found in many household and industrial-strength cleaning solutions.

Ammonia contains nitrogen, which mixes with other elements in your body, including carbon, hydrogen, and oxygen, to form urea. Urea is a waste product that is excreted by the kidneys when you urinate. The urine urea nitrogen test determines how much urea is in the urine to assess the amount of protein breakdown.

Zeolite formulated for freshwater aquarium use will readily absorb ammonia, making it a useful media when dealing with ammonia spikes or potential spikes. It is important to know that zeolite does not remove every undesirable toxin in your tank, nor does it work forever.

Ammonia can act as an aerosol, or teensy particles suspended in the atmosphere. Aerosols often act as "cloud seeds" around which cloud droplets can form. Aerosols are the smallest particles known to contribute to cloud formation, and they also appear to influence the properties of existing clouds, the researchers said.

While there is no real danger in mixing ammonia and vinegar, it's often counterproductive. Because vinegar is acidic and ammonia basic, they cancel each other out, essentially creating salt water and robbing both components of their cleaning properties.

Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. However, the reaction is reversible, and at any one time about 99% of the ammonia is still present as ammonia molecules.
