| Abstract: | In this paper we use iodimetric method to determine SO 3 and sulfuric acid fumes in air of working spots. The SO 3 and sulfuric acid fumes were absorbed in water and react with KI and KIO 3. Starch solution makes solution blue and then SO 3 and sulfuric acid fumes are measured with colorimetric method. |
