Oxalic acid C2H2O4 is a metabolic product of many molds. Although oxalic acid is toxic to humans if ingested, many plants and vegetables contain significant amounts of oxalic acid or oxalate salts. In solution, oxalic acid can be oxidized by air via the following chemical equation: H2C2O4 (aq) + O2 (g) -> H2O2 (l) + 2 CO2 (g) If a plant metabolized enough oxalic acid to produce 3.2L of CO2 on a day when the temperature was 29°C and the pressure was 752 mmHg, a) how many grams of oxalic acid were converted to CO2? b) Given that air is 21% oxygen, what volume of air was needed for the oxidation?

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?
