The crystal structures of sodium bicarbonate, propionic acid and valeric acid
Although Zachariasen was able to determine the gross structure of sodium bicarbonate, his assumptions preclude any conclusions to be drawn concerning the nature of the carbonate group itself. It is therefore the purpose of this paper to reinvestigate the sodium bicarbonate structure employing …
