Question
Solve for Unknown Concentrations using the Best Fit Line and Absorbances
y=mx+b
Example data (however use y= 3605x - 0.006)
y = 4292.9 x - 0.021
Absorbance = 4292.9*concentration - 0.021
So, to find the unknown E concentrations for [FeSCN2+], would plug in the measured absorbance values and solve each for x. That gives the equilibrium concentrations for [FeSCN2+]
