Text: Need help figuring out the one in red boxes. Keeps saying the answer is wrong, but I can't seem to figure out how.
Trial 1:
Concentration of iodide solution (mM): 150.6
Concentration of thiosulfate solution (mM): 94.7
Concentration of hydrogen peroxide solution (mM): 220.5
Temperature of iodide solution (°C): 25.0
Volume of iodide solution I used (mL): 10.0
Volume of thiosulfate solution (S032-) used (mL): 1.0
Volume of DI water used (mL): 2.5
Volume of hydrogen peroxide solution (HO) used (mL): 7.5
Time (s): 28.0
Turned to a blue color: Observations
Initial concentration of iodide in reaction (mM): 71.7
Initial concentration of thiosulfate in reaction (mM): 4.5
Initial concentration of hydrogen peroxide in reaction (mM): 78.75
Initial Rate (mM/s):
