Product description
To determine the sulfur content in steel, a sample of 7.00 g of it was treated with HCl. The released hydrogen sulfide was absorbed by a solution containing a mixture of cadmium and zinc acetates. Then the solution together with the precipitate (CdS + ZnS) was treated with 20.00 ml of iodine solution in the presence of HCl. The excess iodine was titrated with 15.27 ml of thiosulfate solution. How much sulfur (in%) does steel contain if T I / S \u003d 0.0004950 g / ml and 10.20 ml of thiosulfate solution went to titrate 10.00 ml of iodine solution?
