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_forwardWrite balanced chemical equations for the following reactions: (a) cadmium burned in air.

While these sulfides are quite insoluble in water (Ksp of CdS = 1 E -27, Ksp of PbS = 3 E -28), over the years rainwater and snowmelt can slowly dissolve small amounts of these heavy metals, washing them into streams and other natural waters. If these mine tailings are located in an area that is impacted by acid rain, would you expect heavy metal dissolution into natural waters to increase or decrease?
