31. Solution to Chemistry Problem

30. When determining the Cl- ion, a 1.0000 g sample is transferred to a solution in a 100 ml volumetric flask. 20 ml of a 0.1 M silver nitrate solution are added to 25 ml of this solution. The remaining silver nitrate is titrated with 5.5 ml of a 0.1 N potassium thiocyanate solution. Determine the % content of chloride ion in the sample.
