Orthonitrates

HNO4 Peroxonitric acid Unstable, explosive crystals, HOONO2 no solid salts known. (For orthonitrates , N04 , i.e. salts of the unknown orthonitric acid H3NO4, see p. 471 -2)... [Pg.459]

AH° was found to be 27 kcal. and AS was 27 e.u. The large size of the constant compared with the known dissociation of pure sodium carbonate to sodium oxide and carbon dioxide suggests that NO4"3, or orthonitrate is probably formed when oxide ion is placed into fused nitrates. It may well be that the dissociation reaction for pure nitrate should be written ... [Pg.222]

Dr. Duke All of these equilibrium constants involving oxide ion, such as a carbonate going to oxide ion in the nitrates, are much too large. I believe that we are getting orthonitrate here and would like to have some comments on that. [Pg.233]

I feel that orthonitrate is very reasonable. For carbonate I would postulate the analog. [Pg.234]

While orthonitric add itself is unstable, this compound is comparatively stable,... [Pg.564]

A. number of basic lead salts have been considered as salts of some of these acids. Thus, J. Loewe referred the salt 6Pb0.N205.H20 to orthonitric acid, and 3Pb0.N205 to metanitric acid and J. J. Berzelius, and M. E. Chevreul also referred the salt 2Pb0.N206.H20 to metanitric acid ... [Pg.565]

A series of acids can he derived from orthonitrous acid by the substitution of sulphinic, HSO 2> or sulphonic, HS0 3, radicles in place of the hydroxyl-groups. The result with the sulphonic radicles is ... [Pg.670]

Orthonitric acid is still unknown, but its salts Na3N04 and K3NCL have been characterized by X-ray crystallography. The NO4- ion has regular Td symmetry, and its bonding can be represented by resonance structures ... [Pg.577]

Nitric and acetic acids. According to A. Pictet and Genequand [100], acetic acid combines with nitric acid (d = 1.52) to give a kind of mixed orthonitric and acetic anhydride, the so-called diacetylorthonitric acid (b. p. 127.7°C) ... [Pg.42]

The procedure described is a modification of that of Dimroth.8 9-Nitroanthracene has also been prepared by nitration of anthracene with copper nitrate in glacial acetic acid and with diacetyl-orthonitric acid.4 Other methods include direct nitration in acetic acid solution with nitric acid and acetic anhydride.6...

Free orthonitric acid H3NO4, which would be analogous to H3PO4, has not been observed yet. The salts of orthonitric acid, the orthonitrates, contain tetrahedral N04 (d(N ) 139 pm) with somewhat smaller N distances than expected for NAD single bonds. [Pg.3069]
