Sulphur dioxide and sulphites determinationEnvironmental samplesRhodamine-B has been proposed as a simple and sensitive colorimetric reagent for the estimation of sulphur dioxide in air. The air sample containing sulphur dioxide is passed through the absorbing solution of aqueous potassium iodate and N-...
The state of sulphur dioxide in partially dehydrated or dehydrated foods is complex and depends on pH, ionic strength, water activity and concentration, and on the effects of anions and cations on the solubilities of sulphite and disulphite salts. The chemical basis of the preservative action is...
Sulphur dioxide is used 1. in the manufacture of sulphite, hydrogen sulphites and sulphuric acid 2. to sterilize wine and beer making equipment in order to imhibit the growth of moulds and bacteria, and to control wine fermentation 3. in a variety of disin...

The formation of inorganic sulphur oxoanion systems from sulphur dioxide in non-aqueous solventsMetal sulphites which are non-ionic in the unsolvated state can be converted by SO 2 in dimethylsulphoxide (dmso) to ionic metal disulphates, by oxidation with dmso. This conversion of sulphur (IV)...
