A standard solution was put through appropriate dilutions to give the concentrationsof iron shown helow. The iron(I1)-1,IO,phenanthroline complex was thenformed in 25.0mL aliquots of these solutions, following whieh each was dilutedto 50.0 mL. The following absorbances (1.00-cm cells) were recorded at510 nm:(a) Plot a calibration eurve from these data.(b) Use the method of least squares to find an equation relating absorbance andthe concentration of iron(II).(c) Calculate the standard deviation of the slope and intercept
