WebStep 1: Calculate the volume of titrant needed to reach the equivalence point. The first task is to calculate the volume of Ce 4+ needed to reach the titration’s equivalence point. From the reaction’s stoichiometry we know that moles Fe2 + = moles Ce4 + MFe × VFe = MCe × VCe Solving for the volume of Ce 4+ gives the equivalence point volume as WebIodometric methods of analysis have a wide applicability for the following reasons: 1. Potassium iodide, KI, is readily available in high purity. 2. Starch turns blue-black in the presence of iodine. blue-black color disappears, the iodine has been completely reduced to the iodide ion. 3. Iodometric reactions are rapid and quantitative. 4.
