Bond[edit]

Is the Na-C bond ionic? I was under the impression that lines (like we have in our diagram) indicated covalent bonds... Evercat (talk) 22:12, 3 February 2009 (UTC)[reply]

I don't know which diagram you're referring to, but the compound exists as Na⁺CN^–; it is an ionic compound consisting of the sodium and cyanide ions. haz (talk) 14:04, 12 June 2009 (UTC)[reply]

"Conjugate base"[edit]

I've changed the text in the lead section claiming that NaCN is the conjugate base of hydrogen cyanide. This is false – the cyanide ion is the conjugate base of HCN, as that is the product when HCN is deprotonated:

HCN + H₂O ⇌ CN^– + H₃O⁺

NFPA 704[edit]

According to the CDC, the NFPA 704 rating should be 3-0-0. Any reason why it's listed as 4 here? If you have any questions, please contact me at my talk page. Ian Manka 07:31, 10 February 2014 (UTC)[reply]

Sodium Cyanide is Hygroscopic[edit]

Acccording to https://pubchem.ncbi.nlm.nih.gov/compound/sodium_cyanide Sodium Cyanide is Hygroscopic. Though whether this makes it Deliquescent is a different matter (Potassium cyanide is stated as being Deliquescent. Issues concerning the enthalpy of solvation/hydration would appear to be important here.

There should be a page on sodium dicyanoaurate.[edit]

Hi, I am a student doing research on gold leaching when I came across the compound sodium dicyanoaurate. What baffles me is that while there is a page on sodium cyanide, one on gold leaching, and one on potassium dicyanoaurate, there are no pages on this website on specifically the compound sodium dicyanoaurate anywhere. Honestly, I think that this compound has been overlooked, so to make these topics more complete, is it possible to add a page on specifically sodium dicyanoaurate? It does not have to be long, just long enough to explain the basic uses of it. Thanks. 199.243.129.50 (talk) 12:44, 26 April 2023 (UTC)[reply]
