Question

Would the following errors cause an increase or decrease in absorbance and % Transmittance?


insoluble particles were accidentally pipetted into the cuvette with the solution

the cuvette was wet and not prerinsed with the solution.

fingerprints were not wiped off the outside of the cuvette.

the wavelength was changed from maxto max+10 nm.



Most of these are common sense if you think about them in terms of what you did in the lab. Please tell us what you think the answers are and why you think that and we shall try to critique your thoughts.

A increase and T decrease

Answer 1

1. decrease absorbance and decrease % transmittance
2. decrease absorbance and increase % transmittance
3. increase absorbance and decrease % transmittance
4. decrease absorbance and increase % transmittance

Answer 2

1.) Increase absorbance & decrease % transmittance

all the other answer above are correct
