Former good articleAmmonia was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

What? edit

"It is estimated that around 40% of the nitrogen in human beings originally comes from industrial ammonia production." This is illogical.

"As such, its importance can hardly be overstated." Weasel Words. — Preceding unsigned comment added by 203.59.215.99 (talk) 07:19, 30 September 2022 (UTC)Reply

why illogical? 92.7.35.194 (talk) 16:59, 30 September 2022 (UTC)Reply
Its logically and I can see how it could happen (considering fertilizers used to raise crops for human and live stock consumption), but its unreferenced and likely not correct.Hardyplants (talk) 03:04, 4 October 2022 (UTC)Reply

Fuel section - CO2 vs GHG emissions edit

In the fuel section talks about CO2 emissions, but the important metric for climate considerations is CO2-equivalent. While burning a compound that does not contain carbon will not emit CO2, it can certainly lead to nitrous oxide emissions, a potent green house gas. The section needs to edited to reflect the true climate impact. The environmental and health impact from NOx emissions also needs further discussion in this section.

I added that as of 2022, however, significant amounts of NOx are produced. Hope others will add more Chidgk1 (talk) 18:39, 16 December 2022 (UTC)Reply

Image of ammonia (maybe liquid) edit

I think that an image should be added (given how important ammonia is), possibly similar to the pages for nitrogen or oxygen where the image shows the condensed liquid boiling. Sticklink (talk) 20:16, 24 January 2023 (UTC)Reply

I've checked commons and the existing options are poor. Aqueous ammonia is a common laboratory reagent, so I don't think it would be too hard for someone to take a picture of a Winchester of it . Liquid anhydrous ammonia is trickier and also not very impressive to look at (clear colourless liquid - dull). The only way to make it interesting is to drop a shard of sodium in to make it look like this Project Osprey (talk) 21:48, 24 January 2023 (UTC)Reply

ammonia angle edit

The article indicates that the same source indicates two different H-N-H angles: ... with an experimentally determined bond angle of 106.7° and ... therefore the bond angle is not 109.5°, as expected for a regular tetrahedral arrangement, but 106.8°.

As far as I know, both angles are wrong. In all the literature, I know (e.g. C.E. Mortimer und U. Müller: Chemie – Das Basiswissen der Chemie, page 130), I just saw that it's 107.3°. Can someone confirm that? FailXD (talk) 17:02, 5 September 2023 (UTC)Reply

LD50 edit

The LD50 is given as 0.015 ml per kg, which is far too low. The figure 0.015 would make sense if it referred to ml of liquid ammonia, or mg of ammonia, but not ml of gaseous ammonia. Someone knowledgeable in editing chemboxes should correct this to mg per kg or indicate that it refers to liquid ammonia, rather than the gaseous form ammonia has under standard conditions. Ammonia gas is about 1000 times less dense than liquid ammonia. The ICSC0414 data sheet cited farther down in the chembox gives a permissible level of 14 mg per cubic meter, which is equivalent to 0.014 mg per ml.
