Why isn't baking soda mentioned? That is what baking soda is right.

adverse effects
Eating a large amount of potassium bicarbonate has a laxative effect and I believe can cause excessive gas pressure in the stomach. I would call those adverse effects of overexposure. 69.72.92.188 (talk) 23:34, 26 December 2014 (UTC)

Edit: gas in the intestines is more likely caused by undigested and unprocessed proteins and sugars, due to too little stomach acid available for processing these nutrients. Essentially they would fall under "protein farts", as instead of an overdose on protein, the body now has a lack of stomach acid to process the food. — Preceding unsigned comment added by 2607:FB90:4118:522A:284E:9B0F:24B8:CE14 (talk) 15:03, 6 September 2016 (UTC)

Uses: Dental & Sports
I've heard it said to be more effective as plaque remover than anything else, and soft on the teeth enamel, as it dissolves plaque without the need for brushing. Like salt, it also inhibits bacteria growth and the formation of plaque (due to changing the ph in the mouth to less acidic). It also brightens the teeth.

Few websites mention that potassium bicarbonate is trademarked or something, to be used in toothpaste, which is why no toothpaste company is willing to pay the licenses for it. The only company I'm in doubt about, is "arm and hammer", which clearly has a more salty taste, and increased whiteness without whitener, an indicator of potentially using potassium bicarbonate as additive.

Potassium bicarbonate also lowers muscle soreness, by neutralizing lactic acid in the muscles, as soon as 15 to 20 minutes after taking it? Athletes use this in sprints, to be able to run longer and faster, without getting tired, or have less soreness next day. Quote needed. — Preceding unsigned comment added by 2607:FB90:4118:522A:284E:9B0F:24B8:CE14 (talk) 15:01, 6 September 2016 (UTC)

Medical sourcing guideline (MEDRS) with regard to medical claims
, are you familiar with WP:MEDRS? I'm concerned that this edit may not fit - we like to use academic level review articles rather than news articles for medical discussion. II | (t - c) 02:10, 25 May 2019 (UTC)


 * second reply -- previous reply has vanished

No I am not familiar with it. Thanks for noting it to me. I will look into it, however, my edit has to do with the common substance and that potassium carbonate is a sodium-free substitute for sodium carbonate, which is another common substance used in baking, cleaning, laundry products, home remedies, agriculture, and industry. Neither is marketed as "medicine" and I doubt that one would find academic medical articles on substitution of the sodium-free saleratus, potassium carbonate, rather than sodium bicarbonate. I have reworded the entry, hoping to avoid any assertion that may be misinterpreted as a medical recommendation. Please advise if you feel that is not adequate to resolve your discomfort. _ _ _ _ 83d40m (talk) 14:10, 26 May 2019 (UTC)

Chemical Structure Incorrect?
Looking at the chemical formula KHCO₃, I would expect the chemical structure to have carbon in it. Looking into it further, the change 2018/09/21 modified the image from to, but the two images are different:

https://www.wikidata.org/wiki/Q410529

I would talk with the user Edgar181, but it looks like they were banned.

Should I revert this SVG back to the original PNG (or even create a new SVG identical to the original PNG), or is this new chemical structure accurate?

Solubility in water?
The wikipedia pages in Dutch and German mention a solubility of 333g/L but the English page mentions 22.4 g/100 mL. What is the correct solubility? Markus29 (talk) 10:14, 20 April 2020 (UTC)

Correcting the page to align with IUPAC rules
The name of the compound is potassium hydrogencarbonate. Not potassium bicarbonate, not potassium hydrogen carbonate. It contains a hydrogencarbonate anion. Not two carbonates. Don't use archaic English names back from the time its structure was unknown. Please move the page to the proper title, I am unable to, for some reason. Lajoswinkler (talk) 16:16, 29 July 2021 (UTC)
 * Well, most people call it potassium bicarbonate. Lots of IUPAC rules are ignored here. Many archaic names are retained as well.  Its not a matter of being defiant, but of communicating to users and readers. --Smokefoot (talk) 16:56, 29 July 2021 (UTC)


 * I don't care what "most people" call it. This is an encyclopedia, not a highschool yearbook. Substances have IUPAC names, and if people search for wrong ones, Wikipedia transfers them to the correctly named article where the archaic name is mentioned. Lajoswinkler (talk) 11:07, 13 September 2021 (UTC)


 * Wikipedia is an encyclopedia for a general readership. Worldwide Google Search statistics for the last five years (easily accessible to anyone and a proxy of general interest in the topic) show a consistently higher rate of searching for "potassium bicarbonate" vs "potassium hydrogencarbonate" (https://trends.google.com/trends/explore?date=today%205-y&q=potassium%20bicarbonate,potassium%20hydrogen%20carbonate,potassium%20hydrogencarbonate). GeoGreg (talk) 23:55, 22 April 2022 (UTC)
 * Of course bicarbonate is the search term. There are always fundamentalists (not practitioners) who have all kinds of rules that should be shoved down the throats of the "unclean". --Smokefoot (talk) 04:24, 23 April 2022 (UTC)

“Half a cup per gallon” lol !
This sooo much made me laugh. Can we have it in SI units please ? 84.66.0.156 (talk) 20:36, 10 December 2021 (UTC)

Nomenclature
Why is it called bicarbonate when there is only 1 carbonate? Is it because potassium carbonate was already discovered? Could this be added to the History section? "This chemical name potassium bicarbonate is something of a misnomer. Potassium carbonate (K2CO3) had already been discovered, and potassium bicarbonate was found to have twice as much carbonate per potassium." Or something similar? Munksm (talk) 07:52, 21 September 2022 (UTC)


 * See Bicarbonate for the history of the name. Wollaston talks about "the double dose of carbonic acid contained in it". I presume this double dose is relative to potassium carbonate and ignores the hydrogen present in bicarbonate — perhaps unknown or undetectable by standard methods in those days. The carbonate to potassium ratio in KHCO3 is twice that in K2CO3. --Ben (talk) 08:15, 21 September 2022 (UTC)

Potentially unsubstantiated claims
"Potassium bicarbonate is often found added to club soda to improve taste, and to soften the effect of effervescence." This quote is backed up by which doesn't mention effervescence or club soda at all.

 * The statement supported by that reference was originally about bottled water, but someone changed it. That said, potassium bicarbonate is also used in club soda.--Srleffler (talk) 18:18, 23 December 2023 (UTC)
