Clicking on the "more info" = Hazardous Chemical Database on the Properties panel (= about Safety)doesn't codunct to Potassium carbonat! Please, can you correct this programmation error?

Fixed it, nice catch. Snowmanmelting 18:11, 20 October 2005 (UTC)[reply]

Cream of tartar

The article says that cream of tartar is another name for potassium carbonate, but the link redirects to potassium bitartrate. Which is right? 74.104.224.144 21:48, 9 March 2007 (UTC)[reply]

Solvay process

Is it worth mentioning that potassium carbonate cannot be made by the Solvay process due to the high solubility of potassium bicarbonate? Although I can't find any direct references stating this, I am almost sure this is the case. Chris Barile 23:38, 15 July 2007 (UTC)[reply]

"Highly flammable"

It makes no sense to me that this substance could be highly flammable if it has a red zero in its safety box. Evercat (talk) 18:50, 1 December 2008 (UTC)[reply]

This compound is not flammable ! User:Jjd323 (Talk) introduced the flammable info 10 Nov 2008 with other edits to R-S phrases, while I have not checked these other edits searching background references, they seem OK. Jjd323 must have confused the flammability issue. Power.corrupts (talk) 12:46, 6 December 2008 (UTC)[reply]

Pearl Ash

Directly under the "Applications" heading, the substance Pearl Ash is referred to as both Pearl Ash and Pearlash in a single sentence. Please could this be corrected. —Preceding unsigned comment added by 81.86.124.46 (talk) 12:58, 8 November 2009 (UTC)[reply]

Toxicity

Is this stuff toxic? I just discovered some leaking NiMH batteries, and I'm sure some of the crystals got onto the carpet. Is it OK if a baby crawls around and ends up getting some of it into his mouth? Answer: If I were you, I'd let the Potassium Carbonate dissolve through the floor before you let the infant get it into its system...—Preceding unsigned comment added by 98.231.150.231 (talk) 09:28, 9 February 2010 (UTC)[reply]

The above is right and wrong at the same time: NiMH batteries' electrolyte can be quite toxic because of OTHER chemical components in the electrolyte, but potassium carbonate (the major component of the electrolyte) is essentially safe. Riventree (talk) 11:20, 22 December 2012 (UTC)[reply]

Decomposition?!?

The infobox claims it doesn't boil, but decomposes instead. I can't find any references that agree. Potassium BIcarbonate decomposes, but I'm pretty sure potassium carbonate (like sodium carbonate) will boil. Unfortunately, I don't have the gear to test this theory, so I'm hoping someone else will double-check this data. Riventree (talk) 11:22, 22 December 2012 (UTC)[reply]

Lewis Formula is wrong

The formula showed on the top right image is wrong. There is a double bound between O==O- whereas it should be C==O-. Can anybody fix this? — Preceding unsigned comment added by Walabit (talk • contribs) 09:29, 28 August 2014 (UTC)[reply]

History: Antonio Campanella ?

At present, the History section states: "Potassium carbonate was first identified in 1742 by Antonio Campanella … " This statement was added on 22 December 2005. This claim is almost certainly false.

(1) This claim is not referenced — even more than 10 years after it was first posted.

(2) Although other sites on the Internet repeat this claim — word for word, which suggests that they copied it from Wikipedia — none of those sites reference it either. So apparently no one has been able to find a reference for it, which suggests that none exists — because the claim is false.

(3) If anyone had bothered to check even Wikipedia's article on "Potassium", they would have discovered that potassium was not isolated until 1807 (by English chemist Humphry Davy). How could Antonio Campenella have recognized that potash contained potassium carbonate — before potassium was even known to exist? … or even named?

I am therefore deleting this claim. If someone can substantiate it, they can restore it.

(Insoluble in Ethanol)

It seems odd to me that the reference [2] for this claim is a paper on the solubility of potassium carbonate in methanol. Can somebody find a paper on solubility in ethanol? Or should the claim be changed to (insoluble in methanol)? DABurbank (talk) 21:47, 11 May 2016 (UTC)[reply]
