- The amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine; ClO- is reduced to Cl-. The amount of iodine produced by the redox reaction is determined by titration with sodium thiosulfate, Na2S2O3; I2 is reduced to I-. The sodium thiosulfate is oxidized to sodium tetrathionate, Na2S4O6. In this analysis, potassium iodide was added in excess to 5.00 mL of bleach (d=1.00g/cm3) . If 25.00 mL of 0.0700 M Na2S2O3 was required to reduce all the iodine produced by the bleach back to iodide, what is the mass percent of NaClO in the bleach?arrow_forwardConsider the given Ellingham diagram. At 1000 °C, which among Mg, Al, and Zn can be extracted from its oxide by the reaction: 2C (s) + O₂ (g) → 2CO (g)?arrow_forwardThiosulfate ion (S2O32-) disproportionates in acidic solution to give solid sulfur and aqueous hydrogen sulfite ion (HSO3-) .
