    You should then be able to plot the concentration of the dichromate species over time, in three different ways (one is straight up[dichromate vs. time, the second is ln[dichromate] vs. time, and the third is 1/[dichromate] vs. time).

  • Titrimetric Redox of Iron in an Ore Using Dichomate

    Dichromate solutions are orange-yellow but, at the concentration levels generally utilized, the color is too faint to be used for reliable endpoint detection. Thus, a separate indicator is usually added to aid in the endpoint detection.
