To analyze the Cu(NO3)2 in an experiment we constructed a plot of absorbance vs. concentratio, commonly called a calibratioin curve. The absorbance at the top of the peak (i.e., at the wavelenght of maximum absorbance) was chosen for these measurements. What is the potential advantage of using the wavelength of maxiumum abosrbance, rather than some other wavelength? Can you think of a situation in which you might want to choose a different wavelenght?
