“…Dimerisation of hydrogen sulfite has been investigated in aqueous solution by conductometry, 32 as well as IR, 12,33 UV [6][7][8][9][10]34 and Raman 10,11,[35][36][37][38] spectroscopic techniques. Table 1 summarises the reported values for the dimerisation constant, K D , in the literature.…”

In the current work ultraviolet spectrophotometric titrations at different S(iv) concentrations have been globally analysed using the entire spectral dataset to determine the complete speciation of S(iv) in aqueous solution over a large pH range (from 9.6 to 1). As a result, the dimerisation constant for the formation of disulfite from hydrogen sulfite has been accurately determined. Further, protonated disulfite has been identified and quantified for the first time. In addition, the molar absorptivities of all S(iv) species are also reported over the studied wavelength range.

Oxygen of mass 18 was used as a stable tracer to measure the rate of exchange between the sulfite ion and water as a function of pH and total sulfite concentration. A value for the rate constant of hydration of SOz in aqueous solution was determined. The gross rate constants kl and k-I for the overall reaction k 1 SO2 + H z 0 e H + + HS03-k-1 at 24.7 "C and ionic strength = 0.9 were evaluated from exchange results to be k-I = 2.48 0.27 x lo9 mole-' 1 s-I k, = 1.06 k 0.13 x lo's-' Also, for the first time, rate constants for the pyrosulfite equilibrium kz 2 HS03-Sz05'-+ HZO k-z were obtained kz = 7.00 + 0.21 x 1O2mole-' 1 s-' k-z = 1 0 4~-l at 24.7 "C and ionic strength = 0.9.

“…40 The extensive vibrational spectroscopy studies conducted by Simon and Waldman revealed the presence of bisulte anion (HSO 3 À ), which resulted from the dissolution of SO 2 in water. [41][42][43][44][45] In addition, it has been proven that the existence of NH 3 in hydrated SO 2 clusters accelerates the production of HSO 3…”
