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?
Excess stannous chloride in hot HCI is eliminated by boiling, converting stannous
cation to stannic cation.
Excess hydrogen peroxide in basic solution is eliminated by boiling, converting
hydrogen peroxide to water and oxygen gas.
O Excess solid sodium bismuthate is removed by filtration.
O Excess peroxydisulfate is eliminated by boiling, converting the peroxydisulfate to
sulfate.
Excess silver(I, III) oxide in mineral acid is eliminated by boiling, converting
silver(III) cation to silver(1) cation.
