A 1.389 g sample containing some iron(II) in it was dissolved in 1 M H2SO4, then titrated with 0.0292 permanganate until the reaction solution was a pale yellow. 6.8 mL of 7.9 M H3PO4 were added to the reaction solution to form a colorless complex with the Fe3+ reaction product. The titration was finished when the pale pink of excess...

For each equilibrium sample, calculate the initial
concentrations (assuming no reaction occurred) of SCN–
and Fe3+ based on the dilution factors used.
Enter the absorbance values for each sample.
For the standard solution, assume that, when equilibrium is
reached, the [FeSCN2+]eq is equal to
[SCN–]ini. Why is this a good
assumption?
For the equilibrium solutions, calculate the
[FeSCN2+]eq (Ceq) using...
