How would fingerprints on a cuvette during a visible spectrometry lab affect the concentration reading?AConcentration would be lower, since more light is being reflected and not detected by the spectrometry light sensor.BConcentration would be higher since more light is being reflected or absorbed, increasing the absorbance reading.CConcentration will stay the same since the fingerprints will only deflect the light slightly and not enough to affect the absorbance measurements.DConcentration will be increase since more light is absorbed by the solution, resulting in a decrease in the absorbance measurement.

Fingerprints on a cuvette would affect absorbance and concentration calculation by the fact that fingerprints absorb and scatter light slightly, despite not be readily visible. A cuvette (with fingerprints on it) will give a slightly higher absorbance reading and the measured concentration will be significantly higher than the actual concentration.Hence the required answer is- (B)Concentration would be higher since more light is being reflected or absorbed, increasing the absorbance reading.
