AP Chemistry
3.13 Beer-Lambert Law
A student uses a spectrophotometer to determine the concentration of an unknown \text{CuSO}_4\text{(aq)} solution. After calibrating the instrument with a blank and generating a standard curve of absorbance versus concentration at \text{\lambda}_{\text{max}} = 635\text{ nm}, the student measures the absorbance of the unknown sample. However, the student inadvertently leaves a fingerprint smudge on the clear optical face of the cuvette in the path of the light beam. How does this error affect the calculated concentration of the unknown \text{CuSO}_4\text{(aq)} solution?
