Suppose you measure the absorbance of a yellow dye solution in a 1.00 cm cuvette (b=1.00 cm). The absorbance of the solution at 427 nm is 0.84 . If the molar extinction coefficient of yellow dye at 427 nm is 27400 M–1cm–1, what is the concentration of the solution in M?
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.
