Abstract
Raman spectra of mixtures of hydrochloric acid and ammonium thiocyanate have been determined and separated by means of a curve resolver into contributions due to the thiocyanate ion and the thiocyanic acid molecule. By this meanspKa for the latter species is found to be −1.1±0.3 in aqueous solution at 20°C.
