water, even when coupled with commonly very soluble anions" - the fact that most lead(II) compounds are insoluble is already stated in the lead-in, and the solubility of lead(II) acetate seems of peripheral relevance, unless connected to the importance of lead(II) nitrate for metathesis reactions given there are comparatively few alternatives. Further, lead(II) chloride has an appreciable solubility at RT (unlike the article implies), and the crystal formation characteristics of lead(II) halides seem irrelevant to the aqueous chemistry of lead(II) nitrate - and isn't 'can be beautiful' a judgement, as opposed to a more factual 'have been described as beautiful '. In the final part of this section, the concentrations of the added hydroxide are irrelevant to the chemistry being discussed, and should be removed - the same chemistry would occur with other concentrations. There should also be no 'surprisingly', as this begs the question of 'to whom?'. Simple statements "Lead(II) nitrate solutions form basic nitrates when hydoxide solutions are added. The mixed salt Pb(NO

I moved several of these links to their proper places are references. --- And I added a good reference (Thanks dr Walker) to the aqueous chem section. --- Pricing is typical for laboratory chemicals: 100 to 1000 dollar per container (100-2500 g) and variations thereof (simply googled that). This isn't a commodity product with a global market, so I agree with Grahnbahr that adding this kind of info to this article is not helpful. --- The melting information is indeed doubtful, although often published. Old publications indicate only decomposition about 470 °C (often copied into the 'melting point field') and recent references also show decomposition (sometimes 'flash point') at 290 °C. I made the article show no melting point, and a range of decomposition at 290-470. So I think all you requested points have been implemented or otherwise addressed.
1767:, some good comments. FYI, a 3D visualisation isn't possible as lead(II) nitrate isn't a molecular material - it is ionic, and hence represented by a crystal structure such as the one included in the page. The picometre question really points to the inconsistency of unit usage - these should be pm. But, you're right, if spelled out, they should be pluralised. On the "mole/l", you are correct that the abbreviation "mol" should be used, but this drew another point to my notice - we have g•mol for molar mass but g/cm for density - shouldn't we be consistent and use g•cm? PS: This is another argument for 'L' not 'l', as it allows for mol•L.
354:- The article is improved in an impressiv manner. Some of the conserns about comprehensiveness is still not met. The weak oppose is because it is a point it not easy to find information about the compound, I can't tell where to find it. But it is produced bags up to 1100 kg of the compound for commercial sale. It have to be more to tell about the production. What countries have highest production/Where is it produced? How is it produced (don't tell me it is made tons of lead nitrate in the lab for commercial sale)? It is to easy just to say it isn't more to tell. The article, like it looks today, it is more a GA than a FA.
486:- I believe that this article does not reach FA standards under attribute 1. IMO, the writing can be improved, and some of the chemistry content is questionable from a technical perspective. There are some minor formatting errors that should be fixed (and as I have edited v. little of wikipedia, I'm not sure how this is done), and sections that seem to add little useful information. There is repeated content, and content that I don't understand - and yes, I am a chemist. Having said that, I think the basic content is OK, but not FA standard. Some specific examples:
2094:, another query: When talking about the lead halides, the article states "these crystals appear suddenly, when the solutions dip below the recrystallisation temperature". Recrystallisation temperature seems wrong to me - it is a term I have only seen used in relation to metals and alloys, not cases like this. Would you please provide further comment, or consider a change to something like "... suddenly, requiring only a nucleation site once the temperature of the solution has fallen sufficiently for the solution to be supersaturated"?
1621:. I started with a chemical topic as I felt that I was on safe ground (knowledge wise). Instead of just jumping in and changing things I consider chemically wrong, I voiced suggestions. Believe me when I say that I am not trying to rain on your parade of pushing this article back to FA status - to me, this article had a variety of small flaws and inaccuracies. It is, in my opinion, getting better; however, I will not remove my 'oppose' just because you want me to; I will do so when I believe that a change in position is warranted.
1510:, I have taken your recommendations seriously, and enhanced the article in line with your recommendations, or even as recommended. Most issues you brought forward were, in my humble opinion, not major blocks against FA status, but indeed are appreciated improvement recommendations. Please be invited to add more to wikipedia, per Physchim62, especially here with lifting your Opposition, or otherwise pointing out which issue would otherwise still prevent re-promotion of the article.

Initial sentence is "Lead(II) nitrate is the inorganic salt of nitric acid and lead". Firstly, 'inorganic' seems an odd modification for the term 'salt', which is defined in wikipedia as the product from the neutralisation of an acid and a base - but lead isn't a base. It also seems strange to

There are different views (see talkpages/archives of WP:CHEMS) on wikilinking formulas and reactions. My personal view is not to obscure reactions with wikilinks that (as you point out) might even direct you wrongly. So with pleasure, I added this extra adjusted to the same sections.
