Explain mixture is treated with excess sodium iodide

Reference no: EM13213288

A sample of Au(ClO)3 is contaminated with LiClO. An acidified 0.2000 g of this mixture is treated with excess sodium iodide and subjected to iodometric titration. The sample requires 48.24 ml of 0.08893 mol/L Na2S2O2 to reach the equivalence point. Assuming that the Au^3+ and Li^+ ions are uncreative during the titration, determine the mass percent of LiClO in the sample.
