Cerium(IV) is a strong oxidizing agent commonly used in redox titrations. Which of the following statemnt is/are NOT true for cerium(IV I. A Ce* standard solution is prepared using primary-standard-grade ammonium hexanitratocerate(IV), (NH4)2Ce{NO3), dissolved in ho hydrochloric acid solution. II. Ce** is yellow and Ce3* is colorless. The color change is abrupt enough that Ce** can serve as its own indicator. III. Ce**/Ce* exists in different formal potential in different acids due to the interaction of the anions part of the acid with Ce** IV. Analysis of many organic analyte such as alcohol, aldehydes can be determined using Ce**by an indirect method involving a techniqu back titration of unreacted excess Ce*with standard iron II titrant
