QUESTION 5 4 points Save Answer When measuring the various concentration solutions to build a calibration curve, it is standard practice to measure from the least concentrated to the most concentrated, rinsing the cuvette with the next higher concentration solution each time. If the measurement order was reversed, measuring from higher concentration to lower concentration while rinsing with the next lower concentration each time, what impact may be seen on the measured absorbance? O The measured absorbance may be too low O No impact on the measured absorbance would be observed. O The measured absorbance may be too high.

Explanation / Answer

Answer

The measured absorbance may be too high

Explanation

Rinsing higher concentration solution contaminated cuvette with lower concentration solution will not give effective removal of contaminent, so absorbance value may be too high
