What is the extinction coefficient of CuSO4 and how does it impact the measurement of its absorbance in a solution?

The extinction coefficient of CuSO4 is a measure of how strongly it absorbs light at a specific wavelength. A higher extinction coefficient means that the substance absorbs more light. This impacts the measurement of its absorbance in a solution because a higher extinction coefficient will result in a higher absorbance reading, indicating a higher concentration of CuSO4 in the solution.
