For Redox Titrations,the Oxidation State of the Analyte May Need

question 2

Multiple Choice

For redox titrations,the oxidation state of the analyte may need adjusting.The analyte can be preoxidized with an oxidizing agent to quantitatively oxidize the analyte,with the excess oxidizing agent eliminated to prevent interference with titration.Which of the oxidizing agents is paired with INCORRECT elimination chemistry?

• A)Excess peroxydisulfate is eliminated by boiling,converting the peroxydisulfate to sulfate.
• B)Excess silver(I,III)oxide in mineral acid is eliminated by boiling,converting silver(III)cation to silver(I)cation.
• C)Excess solid sodium bismuthate is removed by filtration.
• D)Excess hydrogen peroxide in basic solution is eliminated by boiling,converting hydrogen peroxide to water and oxygen gas.
• E)Excess stannous chloride in hot HCl is eliminated by boiling,converting stannous cation to stannic cation.
