Question 10 W Cu2+] Absorbance 0.025 0.124 0.050 0.268 3 4 0.100 0.150 0.520 0,680 Using a spectrophotometer, a student measures the absorbance of four solutions of CuSO4 at a given wavelength. The collected data is given in the table above. Which of the following is the most likely explanation for the discrepant data in trial 4 ? (A) The solution was at a lower temperature than the solutions in the other trials. The measurement was made using a different spectrophotometer that uses a cell with a longer path length The solution was saturated and the flow of light through the solution was restricted. The concentration of the solution was actually lower than 0.150 M.
