1. Refer to the calbration curve to the right, Why can't this curve be used to determine the concentration of a Cu(NO3)? solution that measind an absarbanct at 630nm of 0825 ? 2. Aeler to the calibration cunve to the right. Wir cany this curve be used to determine the concritratian of a Cu(No3)) solition that measured an absorbance at 530nm of 0.235 ? 3. Refer to the cabibration curve to the right, Can this curve be uied to predict the absorbance that a 0.350M solution of Nicl? woild have? Ixptain why or why net. 4. Refer to the calibration curve to the right. A student measures an unknown concentration solution of Cu(Wo3)2 and finds it has an absorbance at 630nm of 0.147. Determine the concentration of the unknown as precisely as possible and show your modk below. 1.
