Talk:Bicarbonate

message: Is HCO3- soluble or insoluble?
:Bicarbonates are rather soluble.  An example is that Calcium Bicarbonate is soluble while Calcium Carbonate isn't.  LoyalSoldier 04:53, 21 March 2007 (UTC)

message: What foods have bicarbonate in them?
:Bread, cakes, donuts. Those that raises when you heat them Kboom 12:26, 12 June 2007 (UTC)

message: What is the policy of Wikipedia concerning titles of pages? Since hydrogen carbonate is the more proper name, shouldn't the title be changed to that?
:Both names are correct.   The "Hydrogen" tags are generally used in chemicals with three or more hydrogen atoms. It is just like Acetic acid is suppose to be called ethanoic acid, but people call it acetic acid anyways.  LoyalSoldier 04:55, 21 March 2007 (UTC)
replies: text:  Totally disagree; there's no such thing as 'bicarbonate.' It must have a co-ion, whether that's a hydrogen ion or a metal. The analogous name to acetic acid would be bicarbonate of soda, and even that acknowledges the sodium. What's the process to request a change to a page name?

message: Which does the equilibrum shift toward when applied with heat, bicarbonate or carbonate?
: Under what conditions? Both will decompose when heated, but bicarbonate will do so at a lower temperature. LoyalSoldier 22:46, 20 April 2007 (UTC)
thread_title:  Equilibrium question 

message: At least two of the "citations needed" tags on this page seem to be out of place. The first is on the carbonic acid-bicarbonate equilibrium reaction. This equation is very well-known and should hardly need a citation. The other is the mention of the fact that changes in pH within the body are harmful. The next sentence includes a link to the Wikipedia pages for acidosis and alkalosis, which explain in detail why physiological pH changes are a problem. Isn't a link to a Wikipedia page considered valid as a citation? Madgenberyl (talk) 19:53, 15 May 2012 (UTC)

message: Are there any bicarbonates of metal which dont belong to the alkali or alkaline earth metals like Aluminium, Iron, Lead etc ive never seen any listed  — Preceding unsigned comment added by Custard mustard sandwich (talk • contribs) 18:39, 3 February 2013 (UTC)
thread_title: Bicarbonates of non alkali or alkanine earth metals

message: Correct me if I'm wrong, but given that for carbonic acid, pKa values are 6.367 (pKa1), 10.32 (pKa2), isn't the pKb of bicarbonate 14 - 6.367 = 7.633? pKb is a measure of how much it will react as a base (ie HCO3- +H2O 
 H2CO3 + OH-). The pKb currently listed here is that for carbonate. Adabow (talk) 04:48, 7 June 2013 (UTC)
replies: text: Apparently pKb = 3.7 has to belong to carbonate, but the caveat is that pKa1 = 6.367 for H2CO3 is wrong, so your result is also incorrect. Infobox in the “carbonic acid” article currently demonstrates pKa1 of “H2CO3*”, not a real compound but a summary concentration of actual H2CO3 and (much more abundant) dissolved CO2 – it is explained later in article. Pure H2CO3’s pKa1 is claimed to equal 3.6, much lower (more acidic). IMHO we should simply delete the pKb= value from the infobox. Incnis Mrsi (talk) 07:37, 7 June 2013 (UTC)

message: It would be good if this article explained why the word "bicarbonate" begins with "bi-". I had to google the answer: apparently it's because you need twice as many bicarbonate ions as carbonate ions to neutralise the same amount of acid. But I got that from an unreliable source. Could someone who can provide a reliable source add this? -- Dr Greg  talk  23:25, 31 January 2014 (UTC)
replies: text: To a degree, both, but neither. The claim that is most incorrect is that there is 'twice the amount of carbonate in bicarbonate.' Chemically, a bicarbonate ion is a carbonate ion with the addition of one hydrogen. The hydrogen that's in bicarbonate makes bicarbonate weaker than carbonate by about half. In order to obtain carbonate from bicarbonate, though, twice as much bicarbonate is needed. Two  bicarbonates --> one carbonate, one water, one carbon dioxide
