It is known that the concentration of a substance is 1.00x10^-4 mol/L, e=1.5 x 10^4 l/mol cm. Assuming that the uncertainty of the measured light transmittance is 0.005, what is the measured absorbance of the substance? What is the relative measurement error? If the control absorbance value is 0.7, what concentration should the reference solution be? What is the relative error of the concentration measurement? What is the magnification of the transmittance scale?

Absorbance measurements in the range of A = 0.3 - 2 are considered the most accurate. Why are absorbance measurements of 0.05 and 2.5 considered inaccurate? If the absorbance is too high (A = 2.5), the signal difference between the sample and the reference is too small for an accurate measurement. At A = 2.5, the transmission is too high for an accurate measurement. The difference in the absorbance of the sample and reference is too small at A = 0.05. At A = 2.5, the detector is saturated because too much light is reaching the detector. At A = 2.5, a sufficient amount of light does not reach the detector for an accurate measurement.
The Beer’s Law plot of the standard curve for the equilibrium experiment was determined by plotting? absorbance versus [Fe3+] absorbance versus % transmittance % transmittance versus [FeSCN2+] absorbance versus [FeSCN2+]
