Talk:Racemic acid

The previous version had that "It is sometimes found in grape juice during the making of wine." I removed this because this kind of sometimes reads to me like the encyclopedia throwing up its hands. I'd love to know exactly when it is found, vs. when wine contains the usual chiral acid. Eub 07:34, 1 November 2005 (UTC)

Hello fellow Wikipedians,

I have just added archive links to 1 one external link on Racemic acid. Please take a moment to review my edit. You may add after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add to keep me off the page altogether, but should be used as a last resort. I made the following changes:

A note for actual chemists
Racemic acid is not a mixture of d- and l- tartaric acids as suggested by the text and the graphics - it is a distinct crystalline substance in which d- and l- molecules are packed in regular pairs. Because of this pairing, the crystal is symmetrical. That it is not a mixture of two dissymetric crystal forms is adequately demonstrated by the fact that its melting point (significantly, not given in the article) is 206, whereas the individual enantiomers melt at 174. Honestly - look it up! The Pasteur separations were performed on a salt, and not racemic acid itself. Anyone trying to find out about racemic acid by referring to this article would end up even more ignorant. But I know that expertise is frowned upon by Wikipedia. — Preceding unsigned comment added by 86.144.100.103 (talk) 19:00, 7 May 2022 (UTC)
