Let's see how this'll come up in the logs. Wim van Dorst ( Talk) 19:37, 8 May 2006 (UTC).
It is too short for A-Class yet, but for such a normal compound, there's surprisingly little info. Wim van Dorst ( Talk) 23:57, 11 May 2006 (UTC).

Wim, I have replied on your talk page, not used to this yet-- Bostan 15:20, 23 July 2006 (UTC)
In my opinion, most of what is said under "Aqueous chemistry" should belong to the Pb(II) cation and not to lead nitrate specifically (even though in practice you could have only lead nitrate or lead acetate in aqueous solution). The precipitation of lead iodide or lead hydroxide oxides is not a property of lead nitrate but of the divalent lead cation. What's specific for lead nitrate is then e.g. that it is used in the demonstration of precipitation reactions (where of course lead iodide also may be mentioned) but for closer description of which reactions occur between the lead cation and various anions I think a reference to an article about the cation should be more appropriate.
Plumb dulcis (Sweet lead) is the term from the alchemist. The German word for lead acetate is Bleizucker (Lead suggar). Some quaestions to this: Is there a possible mix up between the words, chemicals or between the languages? Is it possible to mention that Plumb dulcis is called that way because it tastes sweet? -- Stone 12:27, 10 November 2006 (UTC)
The article fails to mention the taste of this compound.
It seems like there should be a space before the parentheses, no? -- Liface 00:38, 8 March 2007 (UTC)
The following was left on the page-rating thingie, so I'm moving it here:
I feel I must query the description of lead(II) nitrate as a "strong, stable oxidizer".
Whilst lead (II) compounds could be reduced to lead metal by strong reducing agents (thus categorizing them as weak oxidizers), they are more commonly thought of as weak reducing agents, that can be oxidized to lead (IV) by strong oxidizers. In any case no examples are brought in the article to demonstrate any oxidizing or reducing properties. (The example given where lead nitrate forms oxygen and dinitrogen tetroxide is not a demonstration of lead ion as an oxidizer, but rather a disproportionation of the nitrate ion.)
Perhaps a better description might be "a stable compound, with weak oxidation and reduction properties". 194.90.190.116 08:31, 8 March 2007 (UTC)
It is an oxidizer, shown by the decomposition to PbO. I copy-edited the text to make this clearer. Thanks for the pointer: It has been in the text since 2003, and not been pointed out before. Wim van Dorst ( Talk) 09:23, 27 December 2007 (UTC).
This page got vandalized, I tried to revert it to the previous version and haven't quite managed it, can someone fix it please? Sorry. Jules 15:12, 8 March 2007 (UTC)
Why is the chemical formula reading Pd instead of Pb? It is beyond my expertise (which is not much) to correct this. Dormroomchemist 08:43, 12 March 2007 (UTC)
lead nitrate in production in USA 1835. The reference is contained in "Progress of America to year 1846" by John Macgregor, pub London 1847 by Whittaker & Co,which can be accessed through Google Books. Interesting but brief article on Chemical establishment in USA. ( Bostan 14:09, 2 October 2007 (UTC))
According to the article the compound was synthesized as early as the 15th century by the German alchymist Andreas Libavius. According to the linked article about Libavius, he lived from 1555 to 1616. Is it linked to wrong person, is it given wrong facts in the other article, or is it wrong facts in this article? I tried to check out the source, but couldn't find anything of interest there... Grrahnbahr 20:40, 11 November 2007 (UTC)
I've summarized the safety section per Wikipedia:WikiProject Chemicals/Style guidelines. I'm dumping the removed text here: -- Rifleman 82 05:10, 14 November 2007 (UTC)
Symptoms include intestinal malfunction, strong abdominal pains, appetite loss, nausea, vomiting and cramps, while longer-term exposure may lead to neurological and renal problems. Lead compounds are known to be cumulative poisons, as more than 90% of absorbed lead is fixed in bone tissue from which it is only slowly released over a period of years.
Children are more efficient at absorbing lead from the gastrointestinal tract than adults, and thus more at risk from lead poisoning. Exposure to lead compounds during pregnancy has been linked to increased rates of spontaneous abortion, fetal malformation and low birth weight. Given the cumulative nature of lead toxicity, children and pregnant women should be exposed to soluble lead compounds as little as possible — this is a legal requirement in many countries. [1]
Due care should be taken before and during handling of lead(II) nitrate, including the use of protective equipment such as eye and face protection and rubber gloves. Experiments with lead(II) nitrate should be conducted in fume hoods, and spillages must not be discharged into the environment (details in the material safety data sheets, as listed under external links).¶

The review procedure was left dangling, and recently this article was demoted from FA to B-Class. It is my intention to work on these topics to further improve the article and have it up as Featured Article again. Please assist. Wim van Dorst ( Talk) 20:56, 25 December 2007 (UTC).
"E.g., lead(II) chloride, lead(II) bromide and lead(II) iodide, collectively known as lead halides, are weakly soluble in water (less than 0.01 mole per litre) at room temperature, and only slightly more closer to the boiling point."
I think this should be changed by "for example" or something similar. This formulation isn't very pleasant. Randomblue ( talk) 21:11, 6 January 2008 (UTC)
Is lead(II) nitrate toxic enough that touching a single drop of the solution (and washing it off after 1 or 2 seconds) would cause fatal poisoning? -- 75.40.206.92 ( talk) 00:50, 4 September 2009 (UTC)
Is this a joke? Stonemason89 ( talk) 15:09, 23 October 2009 (UTC)
I've removed a chunk of material:
Any solution containing the lead(II) cation will react with a solution containing the iodide anion to produce a precipitate of the bright orange-yellow lead(II) iodide. This reaction is often used to demonstrate precipitation, because of the striking colour change observed, under the name Pot-o-Gold or Golden Rain: [1]
Nearly all other lead compounds are insoluble in water, even when coupled with commonly very soluble anions. For example, lead(II) chloride, lead(II) bromide and lead(II) iodide, collectively known as lead halides, are merely weakly soluble in water (less than 0.01 mol/L) at room temperature, and only slightly more soluble when heated. This means that lead(II) nitrate has particular importance as a starting point for the production of insoluble lead compounds via double decomposition.
Hot solutions of lead halides can be brought to precipitation on cooling to create feathery, iridescent crystals suspended in water, the colour of which crystal depends on the particular halide (chloride = white, bromide = buff, iodide = yellow). These crystals appear suddenly, requiring only a nucleation site once the temperature of the solution has fallen sufficiently for the solution to be supersaturated. This effect is used for demonstration of solubility in classrooms. [2]
I'll try to find a way to integrate it into the lead article. -- Rifleman 82 ( talk) 16:25, 28 October 2010 (UTC)

This article has just been reduced by one third. The article has been halved in length since its original promotion to featured article status. How can it meet the comprehensiveness criterion of Wikipedia:Featured article criteria after such a huge reduction? DrKay ( talk) 19:55, 11 October 2019 (UTC)
This is a trial to see if layout can be improved when there is a chem box present. The hazards section of the chem box has been moved to a separate chem box in the hazards section of the article. This has reduced the size of the box at the top of the article and has allowed all graphical material to be right-justified. The readability of the article has consequently been improved considerably. Comments (here) on this split as a prototype for a general approach will be appreciated. Petergans ( talk) 17:09, 15 January 2020 (UTC)
The properties table of the chembox was broken and the raw formatting data was just at the bottom of the page. I moved the information into the preexisting box and removed the broken information and the box to the top of the page.
