Frankie determined the trendline for their Calibration Curve for the relationship between Absorbance and [FeSCN2+] was
y = 3823.3 x − 0.0127
During Part B, Frankie measured the absorbance of Equilibrium Solution 3 as 0.292 a.u. (absorbance units).
Question 1: What is the equilibrium concentration of the [FeSCN2+]?
Anjelica used the absorbance of 0.449 a.u. to determine the equilibrium concentration of [FeSCN2+] for Run 5 was 1.17 x 10-4 M. Previously, Anjelica calculated the initial concentrations of [Fe3+] = 1.00 x 10-3 M and [SCN-] = 1.00 x 10-3 M.
Question 2: What are the equilibrium concentrations of [Fe3+] and [SCN-]?
