60. Solving a chemistry problem

4. How does the value of the redox potential depend on the ratio of the concentrations of the oxidized and reduced forms? Given the values of the standard redox potentials of Fe3 /Fe2 and I2/2I- pairs, indicate in which direction the reaction between them should proceed. Is this reaction suitable for the iodometric determination of Fe3 ions? How is permanganometric determination of oxidizing agents carried out? Describe this using the example of determining KClO3.
