Q:
Calculate the final molarities of the sodium thiosulfate, iodide ion, and hydrogen peroxide for each run. Remember, the initial volume of each component was diluted to 100 mL.
Components:
.36 M sulfuric acid- Run 1 35 mL, Run 2 35 mL, Run 3 35 mL
deionized water- Run 1 48 mL, Run 2 43 mL, Run 3 42 mL
.025 M potassium iodide- Run 1 5 mL, Run 2 10 mL, Run 3 5 mL
.0025 M Sodium thiosulfate- Run 1 10 mL, Run 2 10 mL, Run 3 10 mL
H2O2- Run 1 1 mL, Run 2 1 mL, Run 3 2 ml
