Sažetak
The characteristics of polymeric sulfur nitride, (SN)X, electrodes for the sensing of pH in is reported. The application of this new pH-sensor to titrations of both strong and weak acids with strong base is described. The (SN)X electrode has significant advantages for titrations of weak acids {; ; ; pKa > 9) with a strong base, compared to the classical procedure with the glass electrode. Comparative titration curves and quantitative results for hydrochloric acid, perchloric acid, trifluoroacetic acid, boric acid, p-nitrophenol, resorcinol, glycine, phenol, acetic acid, benzoic acid and propanoic acid with glass electrode and (SN)X electrode are given.
