In redox titrations, an auxiliary agent can be used to unify the oxidation states of analyte. The excess reagents should be removed to prevent interference. Which of the following is Not correct regarding excess auxiliary agents? For peroxydisulfate, the excess reagent is removed by boiling the solution to convert it to sulfate ions. Silver sticks, coils or pwder are removed by taking them or filtering them out of solution. O Solid sodium bismuthate is removed by emoved by boiling the solution. O Hydrogen peroxide is removed by boiling to convert its excess into water and oxygen gas.

Accurately weigh out about 6g copper(ii) sulfate crystals into a weighing boat. Use the copper(ii) sulfate crystals to make up 250cm3 of standardized copper (ii) sulfate solution Pipette 25cm3 of this solution into a conical flask Add 1.5g potassium iodide and swirl thoroughly Titrate this solution with standard 0.1 moldm-3 Na2S2O3 in a burette. When the iodine color fades, add 1 cm3 starch indicator. Use your titration data below to calculate the percentage by mass of copper in the copper(ii) sulfate crystals.
In a similar experiment, the mass of 3 PB tablets was measured to be 3.1823 g. The tablets were crushed, and 2.9801 g of the powder was transferred to a beaker and reacted with HCl.
