P. 1351) found that cryoscopic and electric conductivity measurements showed sodium fulminate to be NaCNO.
Soc. Chem., 1882 , 37, P. 434; 38, p. 60) have also shown that the specific heat of the gas decreases with increase of temperature until it reaches a minimum at about 198-253° C. Cryoscopic determinations of the molecular weight of nitrogen peroxide dissolved in glacial acetic acid show that it corresponds to the molecular formula N204 at low temperatures (W.
The specific rotation also varies with the concentration; this is due to the dissociation of complex molecules into simpler ones, a view confirmed by cryoscopic measurements.
Cryoscopic determinations of its molecular weight show that it is H 2 0 2.
Vapour density and cryoscopic determinations point to the double formula, P406.
Cryoscopic measurements on the sodium salt points to the double formula, but the organic esters appear to be derived from H2P03 (see A.
