Talk:Kjeldahl method

Pronounciation
How do you pronounce "Kjeldahl"? Maybe add this to the intro. Thanks. 74.220.226.50 (talk) 12:44, 23 October 2009 (UTC)

I Think its pronounciation is as "keldal", i.e , The "j" and the "h" are silent. Could someone help about the ((modified kjeldahl method))??????? I think it's about nitrogen in oxidized groups as nitro, etc and nitrogen should be converted first and reduced by a reducing agent as thiosulphate , but I'm not sure.

 * You're wrong. Norwegian pronunciation gives "Shelldahl" or "Chelldahl", since the 'kj' sound is the "Kelldahl" I've heard is incorrect. That is, it's either ich-laut [ç] as in English hue, or [t͡ʃ] as in English check, never [k] as in key. see this The word ski is another that suffers from the same mispronunciation, since in its Norwegian form, it's pronounced much like she. --vuo (talk) 22:15, 22 September 2011 (UTC)

Why is the Norwegian pronunciation given for the name of a Danish person in an English article? Timur lenk (talk) 15:13, 29 December 2011 (UTC)

Merger proposal
Total Kjeldahl Nitrogen should be included in Kjeldahl method because the pages are redundant. Neonfuzz (talk) 22:10, 21 September 2011 (UTC)
 * Agree. Kjedahl article needs to explain the term TKN, but TKN doesn't need its own article. ike9898 (talk) 20:39, 26 September 2011 (UTC)
 * Did the merger. See if it is OK> Roshan220195 (talk) 22:25, 2 April 2012 (UTC)
 * Does this article need the link to TKN?Beckejac (talk) 16:36, 10 April 2012 (UTC)

Back-titration reaction
Back-titration reaction formula is obviously a wrong one. It's not even balanced.

Here is my suggestion (based only on reaction logic, no practical evidence):
 * B(OH)3 + H2O + Na2CO3 → NaHCO3(aq) + NaB(OH)4(aq)

And here is the wrong one:
 * B(OH)3 + H2O + Na2CO3 → NaHCO3(aq) + NaB(OH)4(aq) + CO2(g) + H2O

Also NaHCO3 is not quite soluble which makes (aq) a bit questionable. — Preceding unsigned comment added by Chloris6 (talk • contribs) 16:53, 25 December 2014 (UTC)
