Talk:Calcium bicarbonate

Name

I don't think the IUPAC name is calcium bicarbonate. Calcium hydrocarbonate sounds to me more like the IUPAC name since bicarbonate should be called hydrogencarbonate

If the name is changed a pointer shold be left in place to redirect from calcium bicarbonate to whatever other name is chosen, calcium carbonate and calcium bicarbonate are both terms in common usage at the undergraduate level in the US in 2009.JAGIN (talk) 01:38, 26 June 2009 (UTC)

Solubility

16 g/100 ml seems quite high. 16 mg/100 ml seems more likely to me but I don't know and everyone else on www seems to cite Wikipedia. If the solubility is really 16g/100ml what is the carbon dioxide pressure pCO2 then? —Preceding unsigned comment added by 150.227.15.253 (talk) 16:09, 12 May 2011 (UTC)

Both German and English wiki seems to have this number wrong as we've figured out on Czech wiki. It should be between 10 and 200 mg/100 ml in my opinion. See Carbonate chemistry of aquatic systems by Loewenthal and Marais. --Dvorapa (talk) 20:47, 3 June 2019 (UTC)

The figure of 16 g/100ml appears to have been added at 20:37, 22 March 2007 (13 years ago) by an unnamed person using IP address 67.71.89.21 Does anyone know this person or have any information relating to the source of this data? Jerryjoynson (talk) 10:02, 20 November 2020 (UTC)

Our unpublished research indicates that the solubility limit is around 1g/L of calcium carbonate (=1.6 g/L calcium bicarbonate = 0.16 g/100mL) in fresh water at a pH around 7 and with a dissolved CO2 content in approximate equilibrium with the atmosphere. The solubility limit varies significantly with pH and so it is not possible to provide a single definitive figure without reference to pH and pCO2. 192.228.133.211 (talk) 11:06, 1 September 2022 (UTC)

Hypothetical

This is a hypotetical chemical compound WHICH DOES NOT EXIST. Sort of dihydrogenoxidethanol which I would absolutely refuse to drink less it was a glass of scotch ethanol diluted with sparkling water (dihydrogenoxidcarbonate)... — Preceding unsigned comment added by 80.202.36.91 (talk) 13:56, 2 September 2013 (UTC)

Solubility in water ?

Check out the numbers in the tabel Solubility in water is 1.61 gram per 100 ml and not 16.1 per 100 ml. Check out the German version for comparison. --Finn Bjørklid (talk) 14:12, 26 January 2016 (UTC)

Our lab tests (2022) support a value of around 1 gram per Litre of limestone (=1.6 g/L or 0.16g/100mL calcium bicarbonate) which 1/100th of the figure presented, at around pH7 and for water that has a CO2 concentration in approximate equilibrium with the atmosphere. The solubility varies according to pH (solubility increasing as pH falls), so there is not a single value. Our results have not been published and so are, unfortunately, not available. 192.228.133.211 (talk) 10:55, 1 September 2022 (UTC)

"Other Names

There is a clear mistake in this section, baking soda is a common name for sodium bicarbonate, not calcium bicarbonate — Preceding unsigned comment added by 122.61.202.122 (talk) 09:43, 1 May 2018 (UTC)
